Why HTML/XHTML Verification is Required?

There are various reasons to verify your web page before hosting it over the internet.

Any web page quality depends on how well you have written your web page.It should be syntactically correct and should pass all the Quality Gates.
When any Search Engine does indexing for your web page content it might get confused if your HTML tags are not written properly and much of the web page content might not be indexed properly.
There might be many HTML tags which you are using in your web page but then have been depreciated and many of the search engines also don't support them.
Consistency, HTML Code Beauty, Process Compliance are always appreciated by good Webmasters.

What Is W3C Compliance?

The W3C is the World Wide Web Consortium and since 1994 the W3C has provided the guidelines by which websites and web pages should be structured and created. Here are the links to validate your web pages:

Validate HTML/XHTML File against W3C Standard HTML/XHTML Validator.
Validate CSS File against W3C Standard CSS Validator.

While doing verification you will get errors along with appropriate reasons. All the validations will be done using XHTML DTD which is a refined version of HTML.

Rules for W3C Compliance:

There are following rules which you should keep in your mind while writing your web pages.

Use the XHTML declaration statements to start every XHTML page:
```
"-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd">
```
Every tag must be closed.
The head and body tags are now mandatory.
Empty tags get a terminating slash. An empty tag is a tag that doesn't require an end tag. Examples include
and
.
```
 is now 
 />.
 is now 
 />. SRC="--"> is now  src="--" />
```
All tags must be lower case. This does not apply to attributes, only tags. For example, both of these formats are acceptable under the XHTML DTD:
```
 color="#ffffcc"> is invalid color="#ffffcc"> is valid color="#FFFFCC"> is also valid
```
All the attribute values should be put with-in double quote.
Tags may not nested
```
Text
```

This is invalidText This is valid

The

If your code contains a &, it must be written as &.

Any use of CSS should use all lower case lettering.

Lesson 9

 href="otherpage.htm" title="Anchor Title">Anchor Text

Here are following important points to notice about anchors:

The Anchor Title plays a very important roles and will be seen by most of the search engines. So your anchor title should have appropriate keywords. Anchor title will help site visitors using a balloon and displaying written text.
The Anchor Text is another important part which should be selected very carefully because this text will be used not only of search engines but also for the navigation purpose. You should try to use best keywords in your anchor text.
The otherpage.htm is the link to another web page. This link could be to external site. But here care should be taken that this web page should exist otherwise it will be called a broken link and broken links give very bad impression to Search Engines as we as to site visitors.

Another example of an anchor could be as follows:

 href="otherpage.htm" title="Anchor Title">
    src="image.gif" alt="keywords" />

In this case Anchor Text has been replaced by an image. So while using an image in place of anchor text it should be checked that you have put alt tag properly.
