What is the best way to position an element at the bottom of a container?

Question

What is the best way to position an element at the bottom of a container?

My dilemma lies in the header div where I need to position a logo and navigation menu. The logo sits on the left side with dimensions of 100x50, while the navigation menu is set to float: right.

How can I ensure that the navigation menu aligns just above the base of the header div? Is there a way to dynamically adjust this positioning based on changes to the logo size, without manually tweaking the margin-top for the nav element? HTML

<div class="container">
    <header class="site-header">
        <div class="site-logo">
        </div><!-- /site-logo -->

        <nav class="site-nav">
        </nav>
    </header>
</div>

CSS

.site-header nav ul {
  float: right;
  border: 1px solid green;
}

div.site-logo {
  float: left;
  width: 100px;
  height: 50px;
  border: 1px solid #000;
}

P.S.: I am hoping to achieve this without relying on javascript.

Answer №1

Here is an example using flexbox, which is much simpler than using absolute positioning and eliminates the need to worry about logo size.

.site-header {
  display: flex;
  justify-content: space-between;
  align-items: flex-end;
  width: 500px;
  height: 50px;
  border: 1px solid #000;
}

div.site-logo {
  width: 100px;
  height: 50px;
  background-color: #00f;
}

div.site-nav {
  width: 300px;
  height: 25px;
  background-color: #f00;
  z-index: 1;
}

<div class="container">
    <header class="site-header">
        <div class="site-logo"></div><!-- /site-logo -->

        <div class="site-nav"></div>
    </header>
</div>

Remember that when using flex, you may need to include vendor prefixes for certain properties in order to support all browsers.

If you want to implement absolute positioning for your navigation menu, remember that it requires the header to have relative positioning:

header { position: relative; }

After that, you can use code similar to this:

.site-header nav ul {
  position: absolute;
  right: 10px; /* adjust as needed */
  top: 10px; /* adjust as needed */
}

To avoid utilizing flex, one easy method is to include padding for the nav section.

padding top
    +
nav height
    +
padding top

This results in the overall height being equivalent to that of the header bar.

To position an element at the bottom of another element, you can use absolute positioning and set the bottom coordinate to 0. This will ensure that there is no gap between the positioned element and the bottom border of its container.

.site-header nav {
  position: absolute;
  bottom: 0;          // Aligned to parent's bottom border...
  right: 0;           // ...and parent's right border.
}

Keep in mind that absolutely positioning an element requires a parent element with positioning, either absolute:

.site-header {
   position: absolute;
}

...or relative, where you need to create a Block Formatting Context (BFC) by setting the overflow property of the relative parent to something other than visible:

.site-header {
   position: relative;
   overflow: hidden;   // Enforce BFC
}
