What are the common bugs, defects or inconsistencies with the standard in IE6 browser, and how to solve them

• IE6 does not support min-height, the solution is to use css hack:

.target {
    min-height: 100px;
    height: auto !important;
    height: 100px;   // IE6下内容高度超过会自动扩展高度
}

• olThe serial numbers inside liare all 1 and do not increment. Workaround: style the lidisplay: list-item;

• The parent element is not positioned overflow: auto;, contains position: relative;child elements, and overflows when the child element is higher than the parent element. Solution: 1) The child element is removed position: relative;; 2) When the positioning cannot be removed for the child element, the parent elementposition: relative;

<style type="text/css">
.outer {
    width: 215px;
    height: 100px;
    border: 1px solid red;
    overflow: auto;
    position: relative;  /* 修复bug */
}
.inner {
    width: 100px;
    height: 200px;
    background-color: purple;
    position: relative;
}
</style>

<div class="outer">
    <div class="inner"></div>
</div>

• IE6 only supports pseudo-classes of alabels. The :hoversolution: use js to monitor mouseenter and mouseleave events for elements, and add classes to achieve the effect:

<style type="text/css">
.p:hover,
.hover {
    background: purple;
}
</style>

<p class="p" id="target">aaaa bbbbb<span>DDDDDDDDDDDd</span> aaaa lkjlkjdf j</p>

<script type="text/javascript">
function addClass(elem, cls) {
    if (elem.className) {
        elem.className += ' ' + cls;
    } else {
        elem.className = cls;
    }
}
function removeClass(elem, cls) {
    var className = ' ' + elem.className + ' ';
    var reg = new RegExp(' +' + cls + ' +', 'g');
    elem.className = className.replace(reg, ' ').replace(/^ +| +$/, '');
}

var target = document.getElementById('target');
if (target.attachEvent) {
    target.attachEvent('onmouseenter', function () {
        addClass(target, 'hover');
    });
    target.attachEvent('onmouseleave', function () {
        removeClass(target, 'hover');
    })
}
</script>

• IE5-8 does not support opacity, the solution:

.opacity {
    opacity: 0.4
    filter: alpha(opacity=60); /* for IE5-7 */
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=60)"; /* for IE 8*/
}

• When IE6 is set to heightless than font-sizethe height value font-size, the solution:font-size: 0;
• IE6 does not support PNG transparent background, solution: use gif image under IE6
• IE6-7 does not support display: inline-blockthe solution: set inline and trigger hasLayout

    display: inline-block;
    *display: inline;
    *zoom: 1;

• Under IE6, the margin of a floating element in the floating direction that touches the border of the parent element doubles. Solution: 1) Use padding to control the spacing. 2) Floating elements display: inline;solve the problem in this way without any side effects: the CSS standard stipulates that the display:inline of floating elements will be automatically adjusted to block
• By setting the width of the block-level element and the left and right margins to auto, IE6 cannot achieve horizontal centering. The solution: set it for the parent elementtext-align: center;
