There are two kinds of css failure:
1. The css has errors in it that prevent correct rendering.
2. The css renders, but not the way the page creator wants.

1. Look for the following css errors...

You are designing for the quirks mode of the browsers without the doctype. If you are in quirks mode, the browsers do weird things.

Standard mode puts the surrounding styles (margin, border,...

The xml line is not necessary, and causes errors on some browsers.

Look for styles containing both a size style (width, height) and a nonzero surrounding style (margin,. border, padding). These...

There is now a reason to use tables and css for layout, instead of divs and css.

Employers now prefer the table method. Our technical school instructors are now teaching this, instead of div and...

0px is an invalid style. Place units of measure on nonzero values that need them. Do not place units of measure on zero values. It causes some browsers to throw the entire style away.

One page could then contain a link to the other, in a place where it is seen immediately.

Actually, I don't wrote for mobile devices, because I wish that every one of them would be crushed by...

I found two the validation service won't find:

1. You have an 0px style value in your p tag style. This is invalid in Firefox, and causes the entire p tag style to be thrown away. There may be...

You have invalid code that causes FF to throw out the style it is in.

Zero values in styles must NOT have units of measures. Your 0px entries cause the style it is in to be thrown away by the...

Both the center tag and the align= parameter are deprecated. They will stop working sometime in the near future, when HTML 4 is no longer supported. They do not work at all in XHTML now. Please don't...

You have an improper nesting. The ul tag pair can't be inside a p tag pair. It kept the p tag pair from wrapping around the image.

Let's get rid of this "table vs css" idea. It's bogus.

Use table for tabular data, and other things that must be in clear rows and columns. You can use css to format the table nicer. Even rows of...

I see some things:

- You have an absolute size and a surrounding style in the same style entry. Don't put padding and width in the same block object. You can put a padding of 0 in such a style...

You need a lot of little pages, not one huge one. Navigate between them with links.

I have done it. There is a trick to it:

Don't use the same block element for both something using a defined width or size (either absolute or relative), and a surrounding style (margin, border, or...

The problem with the non-table methods is that they fall apart when the browser window size is different than the size planned for. Instead of making page image scroll (as it should), the browser...

It does matter in Firefox, which follows the W3C standard. Firefox does not recognize uppercase or mixed case versions of styles and attributes in doctypes that prohibit them.

The style "height"...
