What are the ways to create animation using CSS3?

The launch of CSS3 was pinnacle to the current change in usage of CSS for developing web animations. Before which, people used resources such as Flash and JavaScript for designing and developing such animations, which includes animated images. There were certain aspects to CSS3 that made creating animations through it so much easier and so much fun. Let’s have a brief look at these aspects now.

CSS3-aniTo begin with, there are two components – the “styles” and “keyframes”. These components make using CSS an apt option for developing animations. How they make it happen is as follows:

  • A “style” describes the CSS animation.
  • A “keyframe” indicates the flow of animation styles from beginning through the end.

Advantages of CSS3 Animations

The following three features are major advantages, which the CSS animations have over other traditional animation techniques (which are script-driven).

  • CSS makes it easy to create simple animations; also, one would not need to have knowledge on JavaScript or similar tools to work with CSS.
  • Unlike JavaScript animations, which runs poorly even the simple animations (when not well made), the CSS animations run really well even when the system’s under moderate load. This is made possible by the rendering engine, which utilizes frame-skipping techniques to maintain performance and smoothness.
  • Having the browsers themselves control the flow of animations (such as animation refresh rates, etc), has lead to best performance optimization and smoother animation flow.

Creating the Animations

Creating a sequence of CSS animation involves using the style component to set the animation’s properties and sub-properties. You get to configure the duration and timing of the animation, along with details related to how the sequence of animation should progress. But, you do not get to configure the appearance of these animations using the style, for which purpose you will be using the @keyframes component.

CSS Style

The following are the style properties & sub-properties

  • animation-delay: This helps configure the time delay between different elements of the loaded animation and the sequential animations.
  • animation-direction: This configuration sets the direction of individual animations, and also states if the particular animation will repeat itself in the same sequence or in a different direction on its consecutive runs.
  • animation-duration: Sets the time an animation would take to complete its single cycle.
  • animation-iteration-count: Sets the number of times an animation would repeat itself. If set to infinite, the animation would go on indefinitely.
  • animation-name: This specifies the at-rule name, which describes an animation’s keyframes.
  • animation-play-state: You can configure an animation’s pause/play status.
  • animation-timing-function: With this configuration, you can establish the acceleration curves of the animation, setting its keyframes transitions.
  • animation-fill-mode: This configures the values applied to an animation, (before & after it’s execution).

CSS @keyframes

As mentioned before, the keyframes allow you to configure the animation’s appearance. For this, you will need to setup at least two (at-rule) keyframes. These keyframes represent how individual elements of the animation render themselves within a set time frame.

This time frame is denoted by a “percentage” system by the keyframes. A 0% represents the start of an animation, and 100% represents the finish; they are given as from/0% and to/100% respectively. Though both these are optional, they are very important, and thus, the browser by default computes all the attributes of the animation and starts and finishes it accordingly, when the values are not provided.

The following are CSS3 animation examples, which should give you a brief understanding of how this works.

Example 1:
25% {
font-size: 200%;
margin-right: 75%;
width: 200%;
}
This example shows that at 25% of the animation, the header will have the right margin at 75%, with the width being 200%.

Example 2:
from {
margin-right: 100%;
width: 500%;
}
to {
margin-right: 0%;
width: 100%;
}

This example has two keyframes; first occurring at 0% and the second at 100% (by default, since the values aren’t provided); this effectively starts and finishes an animation. The right margin is at 100% with a width of 500% at the start of the animation, and ends at 0% of the right margin with 100% width. Therefore, the browser animates a header from left edge to the right edge.

With that, by including additional keyframes you can add intermediate steps and thus, amend the CSS3 animations as per your requirements.

CSS 3:

CSS3 or Cascading Style Sheet 3 is a style sheet language that specifies style formatting, such as color, font, size and layout, for websites. This technique is mostly used in HTML pages. However, unlike HTML, CSS mainly focuses on the design and style of a website rather than its content. The main purpose of using CSS is to make changes on every page on a website without rewriting the code.

Even though CSS3 is not supported by all browsers that are available now, it is becoming very popular because it makes website changes so much easier, when compared with its previous version or JavaScript plugins.

•    Just like normal text, you can be able to add a shadow to HTML text that can be highlighted. Using CSS3, you can change the shadow blur, the shadow angle, and the shadow color in CSS.
•    The property “opacity” can make elements more transparent. You can set the opacity of an image in an image editor and then save it with transparency enabled.
•    With CSS3, you can create gradients right in the browser as soon as you load the web page.

Why use CSS3?

In fact, there is no high demand of innovation that CSS3 was developed, however, the possibilities that CSS3 could be able to provide for us. Before CSS3 has been introduced, web designers can able to create CSS to meet the expected result using images and markup. But, now, with CSS3, they can be able to create the same effects as layout images and extra markup with less effort and more dynamics. This not only helps in making changes easily, but also decreases the size of a web page with less number of images.

Conclusion:

Hence, the combination of both HTML5 and CSS3 are very powerful and can create incredible, high-quality solutions. So, it is mandatory for you to learn them and start using them from today, otherwise you will fall behind your competitors.
