HTML

<div class="left-div">
    &nbsp;
</div>
<div class="right-div">
    My requirements are <b>[A]</b> Content in the two divs should line up at the top, <b>[B]</b> Long text in right-div should not wrap underneath left-div, and <b>[C]</b> I do not want to specify a width of right-div. I don't want to set the width of right-div because this markup needs to work within different widths.
</div>

CSS

.left-div {
    float: left;
    width: 100px;
    height: 20px;
    margin-right: 8px;
    background-color: linen;
}
.right-div {
    margin-left: 108px;
    background-color: lime;
}
