Codes for css design and validator
Fixing bugs in CSS
A high-quality web designer has to undergo every time he or she codes a page using CSS for design. Web Standards is the only way to go and it must be an obvious option when you take your job serious.
Confirm your markup is well structured
Make sure your markup is finely ordered, in other words make use of the suitable markup for the appropriate content. Apply headings for titles, paragraphs for blocks of text, ordered and unordered lists to sum things up in list form or for your navigation, field sets in combination with legend and label elements for forms… Finally, use tables only for what they are used for, tabular data.
Validate your markup
It’s not pretty much the green check mark in the bottom right hand corner of your browser or 0 errors or warning on the W3C Validator that matters. This is only an additional check and a confirmation that your code validates. The W3C markup validator or W3C CSS validator should be your tools to make your page an error free. Tools that facilitate you to create the right coding, but consider that this is just a machine that runs a test for you. Some coding faults, for instance using the incorrect or structure-less code for certain content will not be seen as an error by this machine, so make sure this is in order. Validate the pages is an absolute necessity before you begin to fix any CSS layout problems.
