IE Bug Fixes
1- Bug Fix: IE Double Margin Float Bug- It’s an Internet Explorer-exclusive bug wherein an element that is floated – and given a margin in the same direction as the float – ends up with twice the specified margin size. The fix is extremely simple. All you have to do is apply a display: inline rule to your floated element. So you simply go from something like this:
#content {
float: left;
width: 500px;
padding: 10px 15px;
margin-left: 20px; }
To something like this:
#content {
float: left;
width: 500px;
padding: 10px 15px;
margin-left: 20px;
display:inline;
}
2-
Overcoming the Box Model Hack- If you want to specify a width to any div, do NOT specify padding or margins. Just create an inner div with no width set and specify its padding and margins instead. So instead of doing this:
#main-div{
width: 150px;
border: 5px;
padding: 20px;
}
Do something like this:
#main-div{
width: 150px;
}
#main-div div{
border: 5px;
padding: 20px;
}
3-
Min-height attribute ignored in IE- “min-height” attribute works well in Firefox but IE ignores it. IE’s height act as FF’s min-height. Note: in IE 7 problem was fixed.

.container {
width:20em;
padding:0.5em;
border:1px solid #000;
min-height:8em;
height:auto;
}
/* for Internet Explorer */
/*\*/
* html .container {
height: 8em;
}

Autopopulating text input fields with JavaScript- Sometimes we need to explain to users what they are supposed to enter into text input fields. One common workaround when no label can be displayed is to put some placeholder text in the text field and let that act as the label. This tutorial introduces a nice solution, with JavaScript enabled, the label element is hidden and the value of the input element’s title attribute is copied to the value attribute. If JavaScript is disabled, the label is displayed above the text input, which is left empty. A simple demo, where you can see this in action is
here.

display: none
}
Your tag should look like this:
