Mysterious problem with CSS and Internet Explorer 7_问答_开发者

I think the myth that IE is a nightmare for web designers its true. IE7 is adding me some mysterious padding or margin on the left and right side of my div#image (the gray div) and the paragraph in the div#content is suffering from the CSS propieties of the h2 tag. Thanks in advance!

edit: I even tried Eric Meyer's CSS Reset but it didn't work.

edit2: I just discoverted that the h1 which precede div#image is causing the problem but still can't figure out why.

     <p>Create a web site easily with this online HTML generator. Follow the steps below to create web pages then click "view html page" to test it once it's compl开发者_开发问答eted. You can copy and paste generated code where you wish within the generated document(s). For example: You created an HTML table with 3 rows and 3 columns. You then added a link, which appears below the HTML table. If you want the link inside the HTML table, just cut and paste it inside the table in place of an "ADD TEXT" statement. Any where text,images,or links need to be, there will be a generated "ADD TEXT" statement in the HTML pages.</p>

it says:

<h1>Featured Projects<h2>

are you sure this is your code? it begins with h1, and ends with h2 PS. css box definition in IE7 is different, margins and paddings count as part of width, in newer browsers they are added to width
