Classic DIV CSS case--two columns height adaptive_html/css_WEB-ITnose

I believe many people like to use div css layout very much, whether you are a front-end developer or a back-end programmer, because it has so many benefits and you can control the layout with very little code. Then use CSS to express its form, and separate presentation and style. And in terms of SEO, it can also provide 30% optimization, so why not do it.

Many people will encounter layout problems like the title. There are many solutions. You can use background images to fill it, or use js to control it, but it is not the best solution in the end. It is best to consider DIV and CSS itself. ; html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
