How to Create A Simple Looping Background Colour Animation With CSS

In this tutorial, we are going to create a simple animated background colour animation which loops with pure CSS using keyframes along with various CSS animation properties.

In our example, we are going to set this to the body element. However, you can apply the code to any HTML element of your choice either with an id or class. You can check out the CodePen here if you prefer.

Before we begin, let’s understand the looping animation and how we want the end result to appear:

  • How many background colours do we want to use?
  • How long should total animation duration last?
  • What type of animation type should we use?

In this tutorial, we are going to keep things simple and use:

  • Five different background colours
  • A duration of ten seconds (each color gets displayed two seconds)
  • A linear animation curve (the animation has the same speed from start to end)

We used Coolers.co to generate a nice colour palette for our example:

If you want to use the same colour palette then visit this link.

These are the hex colours for the background animation we used in our example:

  • Sunset Orange: #EE6055;
  • Medium Aquamarine: #60D394;
  • Pale Green: #AAF683;
  • Mellow Yellow: #FFD97D;
  • Vivid Tangerine: #FF9B85;

Right, so lets now dig into it!

How to Create the looping CSS animation

The CSS animations keyframes work in percentages from 0% to 100%. So let’s start by adding the following CSS code:


@keyframes backgroundColorPalette {
  0% {
    background: #ee6055;
  }
  25% {
    background: #60d394;
  }
  50% {
    background: #aaf683;
  }
  75% {
    background: #ffd97d;
  }
  100% {
    background: #ff9b85;
  }
}

We have now created the keyframe property called backgroundColorPalette with five separate intervals; these have been dividing evenly between 0% and 100%.

With this part done, now we can create the CSS rules to animate the body and put our backgroundColorPalette keyframes to action.

Now, let’s add the following CSS animation properties inside your body selector:


body {
  animation-name: backgroundColorPalette;
  animation-duration: 10s;
  animation-iteration-count: infinite;
  animation-direction: alternate;
  animation-timing-function: linear;
}

If you’ve done everything correctly, you will now have a background colour animating evenly between five different colours with a linear animation. Pretty cool aye?

So how does the CSS work exactly?

  • First of all, we added the animation-name property and set the value to backgroundColorPalette. Now the background colour keyframes we previously created were then assigned to the body element.
  • We used the animation-duration property and gave it a value of 10s – This sets the total duration time to ten seconds to process the keyframes we defined.
  • We used the animation-iteration-count property and set the value to infinite. This is so the animation can run in a constant loop and run indefinately.
  • We used the animation-direction property and give it a value of alternate. What this does is it makes the animation play from beginning to end, and from the end to the beginning. We use this property value to avoid an not so attractive jump which happens if you use the normal animation direction value.

And there you have it, liked our tutorial? Then drop us a comment below. If you need any help or further explanation then get in touch!

Live Example

So we decided to create this animation below so you could see how it looks like. We added this HTML; <div id="background-transition"><h3>ANIMATED BACKGROUND</h3></div> then simply replaced body with the ID of the DIV element which in our example is; #background-transition

ANIMATED BACKGROUND

How To Create A Modern Scroll Down Animation Icon With CSS

In this tutorial, we are going to show you how to create a modern scroll down animation which you can easily add to any website.

These types of animations are typically used on websites that have a full-screen header in which you add an animated element to demonstrate that there is more content on the website if you scroll down.

You can have a look at how this animation works on this CodePen we created.

In a previous article, we created a different type of animation, if you want to check that one out then click here.

So let’s begin with this tutorial; for this we just need to add the following HTML and CSS code:


<div id="scroll-wrapper">
  <div id="scroll-wrapper-inner">
    <div id="scroll-title">Scroll</div>
    <div id="scroll-down"></div>
  </div>
</div>

body {
  background: #20232c;
}

#scroll-wrapper {

    width: 100%;
    height: 100%;
    z-index: 9;
    pointer-events: none;
    left: -30%;
}

#scroll-wrapper-inner {
    display: table-cell;
    vertical-align: bottom;
    width: 100%;
    height: 100%;
}

#scroll-down {
    display: block;
    position: relative;
    padding-top: 79px;
    text-align: center;
}

#scroll-title {
    display: block;
    text-transform: uppercase;

        -o-transform: scale(1, 0);
        transform: scale(1, 0);
    }
}

And it’s as simple as that!

With this example, we are centring the scroll down animation. If you want to quickly move the position of this we can add left positioning to the #scroll-wrapper element with either a negative or positive percentage value (depending on where you want this displaying).

We hope you enjoyed this tutorial if you need any help implementing; drop us a comment below!

How to Make the Bootstrap 4 Navbar Dropdown Work on Hover Instead of Click

If you have ever created your own Bootstrap Navbar with a dropdown menu, the first thing you may notice is that you have to click the parent link to reveal the sub-menu. This is an intentional design decision according to Mark Otto:

“The purpose of a hover state is to indicate something is clickable (underlined text) or to provide some quick information (full URL in a tooltip). The purpose of a click is to actually do something, to take explicit action.” – Mark Otto

It’s a valid point but there are always situations where people prefer the hover method. To be honest, not a lot of menus even feature the down chevron, so the hover element makes it clearer that there are sub-menu items to be clicked.

In this tutorial, we are going to be using Bootstrap 4 with the Jumbotron template as an example to show you how simple it is to achieve.

Prefer to dive straight into the CodePen, then click here.

Let’s Begin

Okay, let’s say we have the following HTML markup:


   <nav class="navbar navbar-expand-md navbar-dark fixed-top bg-dark">
  <a class="navbar-brand" href="#">Navbar</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarsExampleDefault">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
      <li class="nav-item">
        <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
      </li>
      <li class="nav-item dropdown">
        <a class="nav-link dropdown-toggle" href="#" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Dropdown</a>
        <div class="dropdown-menu" aria-labelledby="dropdown01">
          <a class="dropdown-item" href="#">Action</a>
          <a class="dropdown-item" href="#">Another action</a>
          <a class="dropdown-item" href="#">Something else here</a>
        </div>
      </li>
    </ul>
    <form class="form-inline my-2 my-lg-0">
      <input class="form-control mr-sm-2" type="text" placeholder="Search" aria-label="Search">
      <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
    </form>
  </div>
</nav>

<main role="main">

  <!-- Main jumbotron for a primary marketing message or call to action -->
  <div class="jumbotron">
    <div class="container">
      <h1 class="display-3">Menu Dropdown on Hover</h1>
      <p>Hey ho, so let's make your dropdown menu work on hover instead of click.</p>
      <p><a href="https://silvawebdesigns.com/" target="_blank" class="btn btn-primary btn-lg" role="button" rel="noopener noreferrer">Learn more &raquo;</a></p>
    </div>
  </div>

  <div class="container">
    <!-- Example row of columns -->
    <div class="row">

        <h2>Learn</h2>

      </div>

        <p><a class="btn btn-secondary" href="#" role="button">View details &raquo;</a></p>
      </div>
    </div>

  </div> <!-- /container -->

</main>

<footer class="container">

</footer>

Now, the important part, to get the CSS to work on hover instead of click, we will be adding the following CSS:


body {
    padding-top: 60px;
    padding-bottom: 40px;
}

.dropdown-menu .sub-menu {
    left: 100%;
    position: absolute;
    top: 0;
    visibility: hidden;
    margin-top: -1px;
}

.dropdown-menu li:hover .sub-menu {
    visibility: visible;
}

.dropdown:hover .dropdown-menu {
    display: block;
}

.nav-tabs .dropdown-menu, .nav-pills .dropdown-menu, .navbar .dropdown-menu {
    margin-top: 0;
}

.navbar .sub-menu:before {
    border-bottom: 7px solid transparent;
    border-left: none;
    border-right: 7px solid rgba(0, 0, 0, 0.2);
    border-top: 7px solid transparent;
    left: -7px;
    top: 10px;
}
.navbar .sub-menu:after {
    border-top: 6px solid transparent;
    border-left: none;
    border-right: 6px solid #fff;
    border-bottom: 6px solid transparent;
    left: 10px;
    top: 11px;
    left: -6px;
}

The key feature of the CSS is simply adding display: block; to the following class element; .dropdown:hover .dropdown-menu

And it’s really as simple as that.

We will need to include the Bootstrap Assets which as of the time of writing, the latest are:

With the CSS code, simply add the stylesheet <link> into your <head> before all other stylesheets to load your CSS.


<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css" integrity="sha384-JcKb8q3iqJ61gNV9KGb8thSsNjpSL0n8PARn9HuZOnIxN0hoP+VmmDGMN5t9UJ0Z" crossorigin="anonymous">

The with the JS, they require jQuery, and their own JavaScript plugins. Place the following scripts near the end of your pages, right before the closing tag, to enable them. jQuery must come first, then the Bootstrap JavaScript plugins.

Bootstrap uses the jQuery’s slim build, but the full version is also supported:


<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/umd/popper.min.js" integrity="sha384-9/reFTGAW83EW2RDu2S0VKaIzap3H66lZH81PoYlFhbGU+6BZp6G7niu735Sk7lN" crossorigin="anonymous"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js" integrity="sha384-B4gt1jrGC7Jh4AgTPSdUtOBvfO8shuf57BaghqFfPlYxofvL8/KUEfYiJOMMV+rV" crossorigin="anonymous"></script>

And there we have it, it’s as simple as that really! Some common problems can be due to the order/positioning of the CSS/JS files, but other than that, it’s a simple feature to implement. You can also make it a bit fancier as well and add some animations into the mix to make the dropdown menu slide down/up. If you would like any help with this, don’t hesitate to get back to us in the comments and we’ll show you how it’s done.

We hope you’ve enjoyed this article and happy coding devs!
