What technique I should use for this web UI feature? (HTML frame or table or others)

I am not quite experie开发者_开发百科nced with web UI design, so I ask here for some opinions of the UI feature I am currently working on. Basically, I would like to know which techniques I should use for the following feature:

I would like to implement a page, the left side of the page occupy 1/3 width of the page, and contain text field, buttons and checkboxes. The right side of the page occupy 2/3 width of the page, it will show some dynamic content based on the left side user input. The right side of the page is mainly implemented by using javascript, jQuery and ajax.

Should I use HTML frame for left and right sides of the page or should I just use a table to divide the page to two parts? or what else? which is better?

You should use neither.

Instead, you should use a combination of the <div> tag for the markup and CSS to define the desired layout.

Never ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever use frames.
