You need to refer to the specification to understand this. If your element is not positionned using position:absolute then you need to consider this section where you can read: If both ‘margin-left’ and ‘margin-right’ are ‘auto’, their used values are equal. This horizontally centers the element with respect to the edges of the containing block. … Read more

The text-overflow property only affects content that is overflowing a block container element in its inline progression direction MDN For text-overflow to work, specifying text-overflow: ellipsis alone will not do any good – you should use the following styles together: overflow: hidden; white-space: nowrap; text-overflow: ellipsis; span, div, th, td { overflow: hidden; white-space: nowrap; … Read more
You probably can’t. Here’s something that comes close. You won’t get content to flow around it if there’s space below. .stuck { position: fixed; top: 10px; left: 10px; bottom: 10px; width: 180px; background-color: #eee; overflow-y: scroll; } .stuck p { margin: 10px; } .not-stuck { margin-left: 200px; } <div class=”stuck”> <p>Lorem ipsum dolor sit amet, … Read more
The problem with using height:100% is that it will be 100% of the page instead of 100% of the window (as you would probably expect it to be). This will cause the problem that you’re seeing, because the non-fixed content is long enough to include the fixed content with 100% height without requiring a scroll … Read more
position: relative does not work on table cells (<td> or display: table-cell). From the spec: http://www.w3.org/TR/CSS21/visuren.html#propdef-position The effect of ‘position:relative’ on table-row-group, table-header-group, table-footer-group, table-row, table-column-group, table-column, table-cell, and table-caption elements is undefined. So, Firefox is doing nothing wrong, although I do wish it would copy other browsers and make this work. To make this … Read more

It’s position is set by default relative to the containing element, therefor in your example, “#container-1” has a padding-left: 20px whereas the rest of the padding is set to 0 making the “default” position of … Read more
the problem you are facing here is, that your section block consumes the full height. so it won’t stick, since it is too large to do so. you would need to put a child element inside your section and give that your sticky attributes, to make it work. based on your example, i simply wrapped … Read more
A trick that works is to position box #2 with position: absolute instead of position: relative. We usually put a position: relative on an outer box (here box #2) when we want an inner box (here box #3) with position: absolute to be positioned relative to the outer box. But remember: for box #3 to … Read more
This is how the painting order works. As described here you have the following order: For all its in-flow, non-positioned, block-level descendants in tree order: If the element is a block, list-item, or other block equivalent: In this step you will print the background and border of the h1 element Otherwise: first for the element, … Read more
