hi!
i m using css and html for designing of my website and if i execute my website on mozilla firefox all alignments are correct, but if i use internet explorer all mess up.. please help

Thanks

You can post some of your codes here. So everyone can see your codes and can find your problem.

I know that feeling :ooh:
There is some difference how IE handles margines and padding. So you should allways look there first.

If you dont provide a link to your site, or post your html and css code, we cant help.

Yes, give us some sample code. A big issue with IE is its box model and how weird it is. Sometimes there are issues with IE that cannot be fixed normally so you have to use a conditional comment for IE.

Special instructions for IE 6 here

yes, i have the problem of margins and padding.
Here i m posting my jsp page and css of project.
in IE alignment of table is changed and padding is also increased automatically.

Don't you have some test web server to provide us with a link?
When finding problem in such a big piece of code seeing things is quite necessary!

Ok first things first. You have a ton of errors in your code. Never used java server pages, but many of the errors are from your commenting. I know <%-- --%> is a commenting technique in jsp.

Regardless of that, you should try to fix these errors as a first step to debugging any rendering issues you have. Good semantic code is just good practice.

start with a browser reset. some people recommend huge resets, but I settle for the simplest one that works.

body {
margin:0;
padding:0
}

Next don't bother adding padding to any div itself, add it to the bits you add inside the div. That usually gets round lots of little problems.
