Achieve a full-page height navigation bar using CSS

Currently in the process of building a website utilizing CSS and HTML, I have successfully added a navigation bar to the left side of the page using this specific CSS code. However, an issue arises when the screen is scrolled down as the navigation bar does not persist.

#navbar {
  background: #a8a599;
  float: left;
  width: 20%;
  height: 100%;
}

My goal is to adjust the height of the navigation bar to match the height of the entire document. While considering JavaScript as a potential solution, my lack of experience with the language presents a challenge in implementing this feature. Initially assuming that setting the height to 100% would suffice in occupying the entire page, it seems to only cover the visible area instead.

Answer 1

Answer №1

100% won't work in this case because the element is floated. To fix this, change the parent container to position: relative and the navbar to position: absolute.

#container{
    position: relative;
}

#navbar {
    background: #a8a599;
    /*float: left; Instead of float, use absolute position*/
    position: absolute;
    width: 20%;
    height: 100%;
}

To resolve the 100% height issue using HTML and CSS, you can use the following code:

body, html {
   height: 100%; 
}

If you prefer to utilize JavaScript for this fix, you can try the following approach:

document.getElementById("navbar").style.height = window.innerHeight;

This will adjust the height of the navBar element to match the height of the browser window.

After spending a good chunk of my time, I finally cracked the solution to this issue! While Derek's answer was close to working, it didn't quite hit the mark as indicated in my comment. The problem arises when the left bar has more content than the main bar, causing the left menu not to stretch properly to accommodate its content. This may not be a common occurrence with just a few options in the menu, but considering my plans for a new administration with numerous modules in the future, it's crucial to address.

The solution lies in utilizing old-school tables with a twist. By applying CSS display properties with values of table, table-row, and table-column, we can effectively resolve the layout issue:

Here is the basic concept:

#page {
    display: table;
    min-height: 100%;
    width: 100%;
}
#pageRow {
    display: table-row;
}
#leftMenu {
    display: table-cell;
    width: 300px;
    background-color: red;
}
#content {
    display: table-cell;
    background-color: blue;
}

To make your #navbar stay fixed on the page, you can adjust the CSS like this:

#navbar {
  background: #a8a599;

  /* removed css */
  /* float: left; */

  /* new css */
  position:fixed;
  top:0;
  left:0;
  /***********/

  width: 20%;
  height: 100%;
}

The float: left; property places an element in relation to the document.

If you remove the float and add position: fixed;, the element will be positioned in relation to the window instead.

You can then adjust the top, bottom, left, or right values as needed.
