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 add Multiple Google Maps Markers using Google Map API JS V3

In today’s tutorial, we are going to show you how you can add multiple markers to a single Google Map. Not just that though, we are also going to show you how to add custom map styles and custom markers to make your map look even better.

I’m just going to go ahead and show the full code we use to do this, then explain what everything does after. So let’s begin…

In our example, we are using the ID map so your HTML will simply look like this:


<div id="map"></div>

The only CSS styles we have added are:


#map {
    position: relative;
    width: 100%;
    height: 350px;
    display: block;
}

Pretty straight forward so far right? If you want a larger map then just increase the height of the #map in your CSS code.

For the Google Map to work, we need to get a Google API Key. If you need instructions on this then visit here.

You will need to include the JavaScript between the before the sript that runs your JS Google Map API code. This will be as follows:


  <script async defer src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap"
  type="text/javascript"></script>

If you are using WordPress, then you can register and enqueue as follows:


    wp_register_script('google-js', 'https://maps.googleapis.com/maps/api/js?v=3.exp&key=AIzaSyBYL8d1Bnuy1b0EwX9iOldIuORnSMSJcjE' );
    wp_enqueue_script('google-js');	

The WordPress code will go in either your theme or child-theme functions.php file if you have one set up.

Now for the JS code…

You will need to call the following code after you load the Google API script mentioned above:


/* Google Map - Contact Us */

if ($("#map").length > 0) {

    function initializeMap() {

        var locations = [
            ['Battersea Park Road', 51.4705666,-0.1728984, 2],
            ['Webbs Road', 51.4575458,-0.165245, 1]
        ];

        var map = new google.maps.Map(document.getElementById('map'), {
            zoom: 14,
            center: new google.maps.LatLng(51.465691,-0.1706737),
            mapTypeId: google.maps.MapTypeId.ROADMAP
        });

        var infowindow = new google.maps.InfoWindow();

        var marker, i;

        var icon = {
            url: "/wp-content/themes/spectrum/assets/img/map-marker.png",
            scaledSize: new google.maps.Size(70, 70)
        }; 

        var marker = new google.maps.Marker({
            map: map,
            animation: google.maps.Animation.DROP,
            icon : icon
        });            

        for (i = 0; i < locations.length; i++) {
            marker = new google.maps.Marker({
                position: new google.maps.LatLng(locations[i][1], locations[i][2]),
                map: map,
                icon : icon
            });

            google.maps.event.addListener(marker, 'click', (function (marker, i) {
                return function () {
                    infowindow.setContent(locations[i][0]);
                    infowindow.open(map, marker);
                }
            })(marker, i));
        }

        var styles = [
            {"featureType":"water","elementType":"geometry","stylers":[{"color":"#e9e9e9"},{"lightness":17}]},{"featureType":"landscape","elementType":"geometry","stylers":[{"color":"#f5f5f5"},{"lightness":20}]},{"featureType":"road.highway","elementType":"geometry.fill","stylers":[{"color":"#ffffff"},{"lightness":17}]},{"featureType":"road.highway","elementType":"geometry.stroke","stylers":[{"color":"#ffffff"},{"lightness":29},{"weight":0.2}]},{"featureType":"road.arterial","elementType":"geometry","stylers":[{"color":"#ffffff"},{"lightness":18}]},{"featureType":"road.local","elementType":"geometry","stylers":[{"color":"#ffffff"},{"lightness":16}]},{"featureType":"poi","elementType":"geometry","stylers":[{"color":"#f5f5f5"},{"lightness":21}]},{"featureType":"poi.park","elementType":"geometry","stylers":[{"color":"#dedede"},{"lightness":21}]},{"elementType":"labels.text.stroke","stylers":[{"visibility":"on"},{"color":"#ffffff"},{"lightness":16}]},{"elementType":"labels.text.fill","stylers":[{"saturation":36},{"color":"#333333"},{"lightness":40}]},{"elementType":"labels.icon","stylers":[{"visibility":"off"}]},{"featureType":"transit","elementType":"geometry","stylers":[{"color":"#f2f2f2"},{"lightness":19}]},{"featureType":"administrative","elementType":"geometry.fill","stylers":[{"color":"#fefefe"},{"lightness":20}]},{"featureType":"administrative","elementType":"geometry.stroke","stylers":[{"color":"#fefefe"},{"lightness":17},{"weight":1.2}]}      
        ];
    
        map.setOptions({styles: styles});            
    
    }
    
    initializeMap();    

} 

So first things first... we added if ($("#map").length > 0) { so that it will only run the JS code on pages that call the map. If you allow it to run on any page, you will find yourself with some console errors, that's why we only run the code on pages that contain the map.

Secondly, we created an array of locations here; var locations = [, you can add as many as you like. Here, we include the info window title, the latitude and longitude coordinates which you can obtain from the URL when you click a location on Google Maps, and also the ID of the location, in our case there are only 2.

In our example, we added two markers, so what we did here is set the 'centre' point to a location that is in the centre of both of the locations so they show correctly on the map. The lat/long value for the centre can be defined here: center: new google.maps.LatLng(51.465691,-0.1706737),.

We then added a custom marker as were not a huge fan of the 'basic' google map markers. You will see on this line; url: "/wp-content/themes/spectrum/assets/img/map-marker.png", that we added the path to our custom marker. We also scaled the marker so that it is double the size so it looks awesome on retina ; ) This was defined on the next line here; scaledSize: new google.maps.Size(70, 70).

We then created a for loop which goes through all the locations and adds each of the pointers on the map using the custom icon that we created.

Finally, we decided to change the default styles of the map. It's always nice to customise this and make it unique. You will see we added var styles = [ and included a long line of code to adjust the map styles. Fear not though, this is very easy to do! Simply head to Snazzy Maps, pick a cool style the matches your website then replace the code with the one provided through their website.

What we end up with our example is a Google Map that looks as follows:

SWEET! We nailed it guys. We sure hope this helps you, if you need any assistance, feel free to drop us a comment below.

As always, happy coding!
