I take it you are trying to raise the code to text ratio on your website is this so?
Ok well if you are looking to increase the code to text ratio on your website in WordPress these are the best things you can do to increase it
Ways to lower the amount of code on a web page
Use CSS layouts instead of table-based layouts.
Take out tags that have no purpose.
Use valid code. A page scoring well everywhere is usually better than one which scores better but fails in most browsers.
Write more text on your posts increases the amount of content that is contained above the fold content.
