CSS Animation Guide: Teach you step by step how to create lightning effects

Introduction:
CSS animation is an indispensable part of modern web design. It can bring vivid effects and interactivity to web pages and enhance user experience. In this guide, we’ll take a closer look at how to use CSS to create a lightning effect, along with specific code examples.

1. Create HTML structure:
First, we need to create an HTML structure to accommodate our lightning effects. We can use a <div> element to wrap the lightning effect and add an ID attribute to it to facilitate our styling in CSS. The following is a sample HTML structure: <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'>&lt;div id=&quot;lightning-effect&quot;&gt;&lt;/div&gt;</pre><div class="contentsignin">Copy after login</div></div><p> 2. Set the basic style: <br>Next, set the basic style of the lightning effect in CSS. We can set the width, height, background color and other attributes for the <code>#lightning-effect element so that we can perform subsequent style settings on it. Here is a basic style example:

#lightning-effect {
  width: 300px;
  height: 500px;
  background-color: black;
  position: relative;
}

3. Create a lightning effect:
Now, we will create a lightning effect by using CSS pseudo-elements and animation properties. First, we can add a ::before pseudo-element to the #lightning-effect element and set its style. We can set attributes such as width, height, border style and position for pseudo elements. We can then use animation properties to achieve the lightning flashing effect.

The following is an example of a lightning effect style:

#lightning-effect::before {
  content: "";
  position: absolute;
  width: 100%;
  height: 100%;
  border: 10px solid white;
  opacity: 0;
  animation: lightning 1s infinite;
}

@keyframes lightning {
  0% {
    opacity: 1;
  }
  
  50% {
    opacity: 0;
  }
  
  100% {
    opacity: 1;
  }
}

Explanation:

• lightning-effect::before: expressed as #lightning-effectPseudo-element ::beforeSet the style of the element.
• content: "": Set the content of the pseudo element to empty.
• position: absolute: Set the position of the pseudo element to absolute positioning so that we can place it freely in the parent element.
• width: 100% and height: 100%: Set the width and height of the pseudo element to be equal to the parent element.
• border: 10px solid white: Set the border of the pseudo element to a white color with a width of 10 pixels.
• opacity: 0: Set the transparency of the pseudo-element to 0, making its initial state invisible.
• animation: lightning 1s infinite: Use lightning animation to set the lightning effect, with a duration of 1 second and an infinite loop.

4. Improve the special effects:
In order to make the lightning special effects look more realistic, we can add some additional styles to them. For example, we can add a blur effect to the lightning effect and use a shadow effect to add dimension to it.

The following is an example of a perfected lightning special effect style:

#lightning-effect::before {
  content: "";
  position: absolute;
  width: 100%;
  height: 100%;
  border: 10px solid white;
  opacity: 0;
  animation: lightning 1s infinite;
  filter: blur(2px);
  box-shadow: 0 0 5px white;
}

Explanation:

• filter: blur(2px): Give lightning Effects adds a 2 pixel blur effect.
• box-shadow: 0 0 5px white: Add a white shadow effect to the lightning effect.

Summary:
Through this guide, we learned how to use CSS to create lightning effects, and how to use pseudo elements and animated properties to achieve the flashing effect of lightning. We also learned how to add extra styling to the lightning effect to make it look more realistic and vivid. I hope this guide was helpful and inspired you to create CSS animations. Come and try to create your own lightning effects!

Reference code:

  
  


  <div id="lightning-effect"></div>

This is a complete HTML file, you can save it as a .html file and open it in the browser to view the lightning effects . You can also make further style adjustments and modifications according to your needs. Good luck!

(Note: The transparency and animation duration in the code example can be adjusted according to actual needs)
