I made a custom search box, it is using a image and the text in FF and Chrome all is lined up correctly, except in IE8 its a bit to high what is the fix to this? FIX: => Line-height: ;
Be sure to check it in Opera too, as it may be messed up there as well... This is why I NEVER play with the padding or height properties on an input - they are not applied the same way in all browsers.
You should play with the padding on some occasions, such as h1, p, etc. as Internet Explorer decides to add default values of them even when they are not specified in the stylesheet. So @OP, check for anywhere that you might need to specify padding:0px; or margin:0px;. This is often the solution for my miss-placed Internet Explorer issues.
