A web standards checklist

The term web standards can mean different things to different people. For some, it is 'table-free sites', for others it is 'using valid code'. However, web standards are much broader than that. A site built to web standards should adhere to standards (HTML, XHTML, XML, CSS, XSLT, DOM, MathML, SVG etc) and pursue best practices (valid code, accessible code, semantically correct code, user-friendly URLs etc).

In other words, a site built to web standards should ideally be lean, clean, CSS-based, accessible, usable and search engine friendly.

About the checklist

This is not an uber-checklist. There are probably many items that could be added. More importantly, it should not be seen as a list of items that must be addressed on every site that you develop. It is simply a guide that can be used:
* to show the breadth of web standards* as a handy tool for developers during the production phase of websites* as an aid for developers who are interested in moving towards web standards

1. Quality of code

1.1 Does the site use a correct Doctype?
A doctype (short for 'document type declaration') informs the validator which version of (X)HTML you're using, and must appear at the very top of every web page. Doctypes are a key component of compliant web pages: your markup and CSS won't validate without them.
http://www.alistapart.com/articles/doctype/
http://www.w3.org/QA/2002/04/valid-dtd-list.html
http://css.maxdesign.com.au/listamatic/about-boxmodel.htm
http://gutfeldt.ch/matthias/articles/doctypeswitch.html

1.2 Does the site use a Character set?
If a user agent (eg. a browser) is unable to detect the character encoding used in a Web document, the user may be presented with unreadable text. This information is particularly important for those maintaining and extending a multilingual site, but declaring the character encoding of the document is important for anyone producing XHTML/HTML or CSS.
http://www.w3.org/International/tutorials/tutorial-char-enc/
http://www.w3.org/International/O-charset.html

1.3 Does the site use Valid (X)HTML?
Valid code will render faster than code with errors. Valid code will render better than invalid code. Browsers are becoming more standards compliant, and it is becoming increasingly necessary to write valid and standards compliant HTML.
http://www.maxdesign.com.au/presentation/sit2003/06.htm
http://validator.w3.org/

1.4 Does the site use Valid CSS?
You need to make sure that there aren't any errors in either your HTML or your CSS, since mistakes in either place can result in botched document appearance.
http://www.meyerweb.com/eric/articles/webrev/199904.html
http://jigsaw.w3.org/css-validator/

1.5 Does the site use any CSS hacks?
Basically, hacks come down to personal choice, the amount of knowledge you have of workarounds, the specific design you are trying to achieve.
http://www.mail-archive.com/wsg@webstandardsgroup.org/msg05823.html
http://css-discuss.incutio.com/?page=CssHack
http://css-discuss.incutio.com/?page=ToHackOrNotToHack
http://centricle.com/ref/css/filters/

1.6 Does the site use unnecessary classes or ids?
I've noticed that developers learning new skills often end up with good CSS but poor XHTML. Specifically, the HTML code tends to be full of unnecessary divs and ids. This results in fairly meaningless HTML and bloated style sheets.
http://www.clagnut.com/blog/228/

1.7 Is the code well structured?
Semantically correct markup uses html elements for their given purpose. Well structured HTML has semantic meaning for a wide range of user agents (browsers without style sheets, text browsers, PDAs, search engines etc.)http://www.maxdesign.com.au/presentation/benefits/index04.htm
http://www.w3.org/2003/12/semantic-extractor.html

1.8 Does the site have any broken links?
Broken links can frustrate users and potentially drive customers away. Broken links can also keep search engines from properly indexing your site.
http://validator.w3.org/checklink

1.9 How does the site perform in terms of speed/page size?
Don't make me wait... That's the message users give us in survey after survey. Even broadband users can suffer the slow-loading blues.
http://www.websiteoptimization.com/speed/

1.10 Does the site have JavaScript errors?
Internet Explore for Windows allows you to turn on a debugger that will pop up a new window and let you know there are javascript errors on your site.
This is available under 'Internet Options' on the Advanced tab.
Uncheck 'Disable script debugging'.

2. Degree of separation between content and presentation

2.1 Does the site use CSS for all presentation aspects (fonts, colour, padding, borders etc)?
Use style sheets to control layout and presentation.
http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-style-sheets

2.2 Are all decorative images in the CSS, or do they appear in the (X)HTML?
The aim for web developers is to remove all presentation from the html code, leaving it clean and semantically correct.
http://www.maxdesign.com.au/presentation/benefits/index07.htm

3. Accessibility for users

3.1 Are "alt" attributes used for all descriptive images?
Provide a text equivalent for every non-text element
CODEhttp://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-text-equivalent

3.2 Does the site use relative units rather than absolute units for text size?
Use relative rather than absolute units in markup language attribute values and style sheet property values'.
http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-relative-units
http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-relative-units
http://www.clagnut.com/blog/348/

3.3 Do any aspects of the layout break if font size is increased?
Try this simple test. Look at your website in a browser that supports easy incrementation of font size. Now increase your browser's font size. And again. And again... Look at your site.
Does the page layout still hold together? It is dangerous for developers to assume that everyone browses using default font sizes.

3.4 Does the site use visible skip menus?
A method shall be provided that permits users to skip repetitive navigation links.
http://www.section508.gov/index.cfm?FuseAction=Content&ID=12

Group related links, identify the group (for user agents), and, until user agents do so, provide a way to bypass the group.
http://www.w3.org/TR/WCAG10-TECHS/#tech-group-links
...blind visitors are not the only ones inconvenienced by too many links in a navigation area. Recall that a mobility-impaired person with poor adaptive technology might be stuck tabbing through that morass.
http://joeclark.org/book/sashay/serialization/Chapter08.html#h4-2020
http://www.niehs.nih.gov/websmith/508/o.htm

3.5 Does the site use accessible forms?
Forms aren't the easiest of things to use for people with disabilities. Navigating around a page with written content is one thing, hopping between form fields and inputting information is another.
http://www.htmldog.com/guides/htmladvanced/forms/
http://www.webstandards.org/learn/tutorials/accessible-forms/01-accessible-forms.html
http://www.accessify.com/tools-and-wizards/accessible-form-builder.asp
http://accessify.com/tutorials/better-accessible-forms.asp

3.6 Does the site use accessible tables?
For data tables, identify row and column headers... For data tables that have two or more logical levels of row or column headers, use markup to associate data cells and header cells.

http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-table-headers
http://www.bcc.ctc.edu/webpublishing/ada/resources/tables.asp
http://www.accessify.com/tools-and-wizards/accessible-table-builder_step1.asp
http://www.webaim.org/techniques/tables/

3.7 Is there sufficient colour brightness/contrasts?
Ensure that foreground and background colour combinations provide sufficient contrast when viewed by someone having colour deficits.
http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-colour-contrast
http://www.juicystudio.com/services/colourcontrast.asp

3.8 Is colour alone used for critical information?
Ensure that all information conveyed with colour is also available without colour, for example from context or markup.
http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-colour-convey

There are basically three types of colour deficiency; Deuteranope (a form of red/green colour deficit), Protanope (another form of red/green colour deficit) and Tritanope (a blue/yellow deficit- very rare).
http://colourfilter.wickline.org/
http://www.toledo-bend.com/colourblind/Ishihara.html
CODEhttp://www.vischeck.com/vischeck/vischeckURL.php

3.9 Is there delayed responsiveness for dropdown menus?
Users with reduced motor skills may find dropdown menus hard to use if responsiveness is set too fast.

3.10 Are all links descriptive?Link text should be meaningful enough to make sense when read out of context - either on its own or as part of a sequence of links. Link text should also be terse.
http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-meaningful-links

4. Accessibility for devices.

4.1 Does the site work acceptably across modern and older browsers?
Before starting to build a CSS-based layout, you should decide which browsers to support and to what level you intend to support them.
http://www.maxdesign.com.au/presentation/process/index_step01.cfm

4.2 Is the content accessible with CSS switched off or not supported?
Some people may visit your site with either a browser that does not support CSS or a browser with CSS switched off. In content is structured well, this will not be an issue.

4.3 Is the content accessible with images switched off or not supported?Some people browse websites with images switched off - especially people on very slow connections. Content should still be accessible for these people.

4.4 Does the site work in text browsers such as Lynx?
This is like a combination of images and CSS switched off. A text-based browser will rely on well structured content to provide meaning.
http://www.delorie.com/web/lynxview

4.5 Does the site work well when printed?
You can take any (X)HTML document and simply style it for print, without having to touch the markup.
http://www.alistapart.com/articles/goingtoprint/
http://www.d.umn.edu/itss/support/Training/Online/webdesign/css.html#print

4.6 Does the site work well in Hand Held devices?
This is a hard one to deal with until hand held devices consistently support their correct media type. However, some layouts work better in current hand-held devices. The importance of supporting hand held devices will depend on target audiences.

4.7 Does the site include detailed metadata?
Metadata is machine understandable information for the web
http://www.w3.org/Metadata/

Metadata is structured information that is created specifically to describe another resource. In other words, metadata is 'data about data'.

4.8 Does the site work well in a range of browser window sizes?
It is a common assumption amongst developers that average screen sizes are increasing. Some developers assume that the average screen size is now 1024px wide. But what about users with smaller screens and users with hand held devices? Are they part of your target audience and are they being disadvantaged?

5. Basic Usability

5.1 Is there a clear visual hierarchy?
Organise and prioritise the contents of a page by using size, prominence and content relationships.
http://www.great-web-design-tips.com/web-site-design/165.html

5.2 Are heading levels easy to distinguish?
Use header elements to convey document structure and use them according to specification.

http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-logical-headings

5.3 Is the site's navigation easy to understand?
Your navigation system should give your visitor a clue as to what page of the site they are currently on and where they can go next.
http://www.1stsitefree.com/design_nav.htm

5.4 Is the site's navigation consistent?
If each page on your site has a consistent style of presentation, visitors will find it easier to navigate between pages and find information
http://www.juicystudio.com/tutorial/accessibility/navigation.asp

5.5 Does the site use consistent and appropriate language?
The use of clear and simple language promotes effective communication. Trying to come across as articulate can be as difficult to read as poorly written grammar, especially if the language used isn't the visitor's primary language.
http://www.juicystudio.com/tutorial/accessibility/clear.asp

5.6 Does the site have a sitemap page and contact page?
Are they easy to find?Most site maps fail to convey multiple levels of the site's information architecture. In usability tests, users often overlook site maps or can't find them. Complexity is also a problem: a map should be a map, not a navigational challenge of its own.
http://www.useit.com/alertbox/20020106.html

5.7 For large sites, is there a search tool?
While search tools are not needed on smaller sites, and some people will not ever use them, site-specific search tools allow users a choice of navigation options.

5.8 Is there a link to the home page on every page in the site?
Some users like to go back to a site's home page after navigating to content within a site. The home page becomes a base camp for these users, allowing them to regroup before exploring new content.

5.9 Are links underlined?
To maximise the perceived affordance of clickability, colour and underline the link text. Users shouldn't have to guess or scrub the page to find out where they can click.
http://www.useit.com/alertbox/20040510.html

5.10 Are visited links clearly defined?
Most important, knowing which pages they've already visited frees users from unintentionally revisiting the same pages over and over again.
http://www.useit.com/alertbox/20040503.html

6. Site management

6.1 Does the site have a meaningful and helpful 404 error page that works from any depth in the site?
You've requested a page - either by typing a URL directly into the address bar or clicking on an out-of-date link and you've found yourself in the middle of cyberspace nowhere. A user-friendly website will give you a helping hand while many others will simply do nothing, relying on the browser's built-in ability to explain what the problem is.
http://www.alistapart.com/articles/perfect404/

6.2 Does the site use friendly URLs?
Most search engines (with a few exceptions - namely Google) will not index any pages that have a question mark or other character (like an ampersand or equals sign) in the URL... what good is a site if no one can find it?
CODEhttp://www.sitepoint.com/article/search-engine-friendly-urls

One of the worst elements of the web from a user interface standpoint is the URL. However, if they're short, logical, and self-correcting, URLs can be acceptably usable
http://www.merges.net/theory/20010305.html
http://www.sitepoint.com/article/search-engine-friendly-urls
http://www.websitegoodies.com/article/32
http://www.merges.net/theory/20010305.html

6.3 Does the site's URL work without "www"?
While this is not critical, and in some cases is not even possible, it is always good to give people the choice of both options. If a user types your domain name without the www and gets no site, this could disadvantage both the user and you.

6.4 Does the site have a favicon?
A Favicon is a multi-resolution image included on nearly all professionally developed sites. The Favicon allows the webmaster to further promote their site, and to create a more customized appearance within a visitor's browser.
http://www.favicon.com/

Favicons are definitely not critical. However, if they are not present, they can cause 404 errors in your logs (site statistics). Browsers like IE will request them from the server when a site is bookmarked. If a favicon isn't available, a 404 error may be generated. Therefore, having a favicon could cut down on favicon specific 404 errors. The same is true of a 'robots.txt' file.

Everyone wants to have such trojan because he
or she want to have access to their victim's hard drive.
The RAT'S (remote access trojans)are very
simple to use.Just make someone run the server
and you get the victim's IP and you have FULL
access to his or her computer.They you can
almost everything it depends of the trojan you use.
But the RAT'S have the common remote access trojan functions like:
keylogger,upload and download function,
make a screen shot and so on.Some people use the
trojans for malicious purposes.
They want just to delete and delete.This is lame.
There are many programs out there
that detects the most common trojans,but new trojans are
coming every day and these programs are not the maximum defense.
The trojans do always the same things.
If the trojan restart every time Windows is loaded that
means it put something in the registry
or in win.ini or in other system file so the trojan can restart.
Also the trojans create some file in
the WINDOWS\SYSTEM directory.The file is always looking
to be something that the victim will think
is a normal WINDOWS executable.Most trojans hide
from the Alt+Ctrl+Del menu

There are programs
that will tell me you exactly the process and the
file from where it comes.Yeah but some trojans
as I told you use fake names and it's a little hard
for some people to understand which process
should they kill.The remote access trojans opens
a port on your computer letting everyone to connect.
Some trojans has options like change the port
and put a password so only the guy that infect you
will be able to use the computer.The change
port option is very good because I'm sure you
don't want your victim to see that port 31337 is open
on their computer.Remote access trojans are
appearing every day and they will continue to appear.
For those that use such trojans: BE CAREFUL
you can infect yourself and they the victim you
wanted to destroy will revenge]

Password Sending Trojans
Moderator's Share and help me in this thread more what u think
what is ur way


purpose of these trojans is to rip all cached
passwords and send them to specified e-mail
without letting the victim about the e-mail.
Most of these trojans don't restart every time Windows
is loaded and most of them use port 25 to
send the e-mail.There are such trojans that e-mail
other information too like ICQ number
computer info and so on.These trojans are dangerous if
you have any passwords cached anywhere on your computer.


Keyloggers {cracker favourite meal }

The only one thing
they do is to log the keys that the victim is pressing
and then check for passwords in the log file.
In the most cases these trojans restart every
time Windows is loaded.They have options
like online and offline recording.In the online recording
they know that the victim is online and
they record everything.But in the offline recording
everything written after Windows start is
recorded and saved on the victims disk waiting for
to be transferred.


Destructive {System attack}
The only one function of these trojans is to
destroy and delete files.This makes them very simple
and easy to use.They can automatically
delete all your .dll or .ini or .exe files on your computer.
These are very dangerous trojans and once
you're infected be sure if you don't disinfect your
computer information will no longer exist.

Virus for damage is One eg of this

Mostly hackers use kL for Attack On System so guys Poste ur detail Too

FTP trojans

These trojans open port 21 on your computer
letting EVERYONE that has a FTP client to connect
to your computer without password and will full upload and download options.



all are dangerous
and you should be careful before using them almost
