Question

I have this problem then I try to float div left,
each block contains same div class (member).

Block goes up if it is on the right hand side, but doesnt work on left.

Any thoughts?

.member {
    float: left;
    position: relative;
    width: 422px;
    margin: 0px 10px 10px 0px;
    height: auto;
}

Answer 1

I suppose you want two columns with blocks of different height.

Then you should one column float to left and the second to the right:

Like this:

.member {
    position: relative;
    width: 422px;
    margin: 0px 10px 10px 0px;
    height: auto;
}

.fl_left {
    float: left;
    clear: left;
}

.fl_right {
    float: right;
    clear: right;
}

HTML:

<div id="left">
    <div class="fl_left">
        <div class="member"></div>
        <div class="member"></div>
    </div>
    <div class="fl_right">
        <div class="member"></div>
        <div class="member"></div>
    </div>
</div>
