<div id="model-response-message-contentrd6f01278905add60" class="markdown markdown-main-panel stronger enable-updated-hr-color" dir="ltr">
<p>Using the basic class bg-test for the height and width of the div element.</p>
<p><code>.bg-test {</code><br /><code>&nbsp; height:300px;</code><br /><code>&nbsp; width:100%;</code><br /><code>&nbsp; margin-bottom:10px;</code><br /><code>}</code></p>
<p>then adding on some classes to this test div to demonstrate each background color.&nbsp;</p>
<p>so to add a <a href="https://kruxor.com/view/cssreference/ruvO9/background/">background </a>color, i added the class bg-color and then to this using the background as a shorthand for the background-color as you can just pass it a color value.&nbsp;</p>
<p><code>.bg-color {</code><br /><code>&nbsp; background:rgba(245,234,566);</code><br /><code>}</code></p>
<p>now we will add some opacity to the background using the class <code>bg-opacity</code> but also still using the bg-test class as this is used for the height and width of the element.&nbsp;</p>
<p><code>.bg-opacity {</code><br /><code>&nbsp; / this sets the opacity to half of the solid color above as we are using rgba /</code><br /><code>&nbsp; background:rgba(245,234,566, 0.5);</code><br /><code>}</code></p>
<p>Then we can add a background image with the following class bg-image and code.&nbsp;</p>
<div><code>/ adding an image as a background and set it to cover the size of the div /</code></div>
<div><code>.bg-image {</code></div>
<div><code>background: url("https://i.imgur.com/GCZCt3q.png") center;</code></div>
<div><code>&nbsp; background-size: cover;</code></div>
<div><code>}</code></div>
<p>If you want to see how the image resizes you can also set the div value to resize which you can see in the last example.&nbsp;</p>
<div><code>.bg-image-resize {</code></div>
<div><code>background: url("https://i.imgur.com/GCZCt3q.png") center;</code></div>
<div><code>&nbsp; background-size: cover;</code></div>
<div><code>&nbsp; resize: both;</code></div>
<div><code>&nbsp; overflow: auto;&nbsp;&nbsp;</code></div>
<div><code>}</code></div>
<p>&nbsp;</p>
<p>Here are the CSS code examples for background properties demonstrated in the video:</p>
<h3>Background Color</h3>
<ul>
<li>
<p><code>background-color</code> [<a class="ng-star-inserted" href="http://www.youtube.com/watch?v=8PAeN-hw33A&amp;t=18" target="blank" rel="noopener">00:18</a>]</p>
</li>
<li>
<p><code>background</code> (as a shorthand for color) [<a class="ng-star-inserted" href="http://www.youtube.com/watch?v=8PAeN-hw33A&amp;t=31" target="blank" rel="noopener">00:31</a>]</p>
</li>
</ul>
<p>&nbsp;</p>
<h3>Background Opacity</h3>
<ul>
<li>
<p>Using <code>RGBA</code> values in the <code>background</code> property to set opacity. For example: <code>background: RGBA(R, G, B, A)</code> where 'A' is the opacity level (e.g., 0.8) [<a class="ng-star-inserted" href="http://www.youtube.com/watch?v=8PAeN-hw33A&amp;t=49" target="blank" rel="noopener">00:49</a>].</p>
</li>
</ul>
<hr />
<p>&nbsp;</p>
<h3>Background Image</h3>
<ul>
<ul>
<li>
<p><code>background: URL('your-image-url')</code> [<a class="ng-star-inserted" href="http://www.youtube.com/watch?v=8PAeN-hw33A&amp;t=75" target="blank" rel="noopener">01:15</a>]</p>
</li>
<li>
<p><code>background-position: center</code> [<a class="ng-star-inserted" href="http://www.youtube.com/watch?v=8PAeN-hw33A&amp;t=83" target="blank" rel="noopener">01:23</a>]</p>
</li>
<li>
<p><code>background-repeat: no-repeat</code> [<a class="ng-star-inserted" href="http://www.youtube.com/watch?v=8PAeN-hw33A&amp;t=87" target="blank" rel="noopener">01:27</a>]</p>
</li>
<li>
<p><code>background-size: cover</code> [<a class="ng-star-inserted" href="http://www.youtube.com/watch?v=8PAeN-hw33A&amp;t=102" target="blank" rel="noopener">01:42</a>]</p>
</li>
<li>
<p><code>background-size: contain</code> [<a class="ng-star-inserted" href="http://www.youtube.com/watch?v=8PAeN-hw33A&amp;t=122" target="blank" rel="noopener">02:02</a>]</p>
</li>
