css - Set position absolute and margin

Question

I would like to set an element's position to absolute and have a margin-bottom, but it seems that the margin-bottom doesn't have an effect.

HTML:

<div id='container'></div>

CSS:

#container {
  border: 1px solid red;
  position: absolute; 
  top: 0px;
  right: 0px;
  width: 300px;
  margin-bottom: 50px; // this line isn't working
}

Answer 1

I know this isn't a very timely answer but there is a way to solve this. You could add a "spacer" element inside the element positioned absolutely with a negative bottom margin and a height that is the same size as the negative bottom margin.

HTML:

<div id="container">
    <div class="spacer"></div>
</div>

CSS:

// same container code, but you should remove the margin-bottom as it has no effect

// spacer code, made it a class as you may need to use it often
.spacer {
    height: 50px;
    margin: 0 0 -50px 0;
    /* margin: 20px 0 -50px 0; use this if you want #container to have a 'bottom padding', in this case of 20px */
    background: transparent; /* you'll need this if #container's parent element has a different background from #container itself */
}
