Dreamweaver browser compatibility issue, What does this mean ?

[eperkins153]

what does this mean and how do I fix it, my website looks fine when i look at in internet explorer and firefox, and I have seen it on multiple computers, and it displays fine.

---------------------------expanding box problem
Any content that does not fit in a fixed-width or -height box causes the box to expand to fit the content rather than letting the content overflow.

Affects: Internet Explorer 6.0
Likelihood: Likely


------------------------extra white space in lists link bug
If a link with display: block and no explicit dimensions is inside a list item, any spaces or linebreaks that follow the list item in the code will cause extra whitespace to appear in the browser.

Affects: Internet Explorer 6.0
Likelihood: Very Likely

------------------------Float drop problem
If a container (including the browser window itself) is not wide enough to accommodate both a float with a specified width and any content with a specified width that follows it, the content after the float will drop below the float rather than wrapping around it.

Affects: Internet Explorer 6.0, 7.0
Likelihood: Likely

any help would be appreciated thanks

Do NOT make the mistake of designing for IE6.

The correct way to design for IE6 is to tell them to upgrade, if you do that you've gone above and beyond the call of duty:

It's like like an illness that just won’t go away. You'd be doing 11% of end users a great favor and 100% of web designers an enormous favor.
