Using CSS3 to realize the dynamic special effect code of button hovering and flashing


We introduced the method of using CSS3 column series attributes to create waterfall flow layout. Interested friends can learn about it~

Let’s take a look at the renderings first

Now let’s study how to achieve this effect:

The first is the HTML part, which defines a div container to wrap the button button, and uses label pairs to contain the button text in the button

<div id="shiny-shadow">
 < button > < span > mouse over < / span > < / button >

Then start to define CSS style for decoration: adjust layout style and color range

#shiny-shadow {
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100vh;
  background: #1c2541;
button {
  border: 2px solid white;
  background: transparent;
  text-transform: uppercase;
  color: white;
  padding: 15px 50px;
  outline: none;
span {
  z-index: 20;

Then make a flashing covering:

Use the: after selector to make a rectangle with transparency and make it absolutely positioned relative to the button button

button {
  position: relative;
button:after {
    content: '';
    display: block;
    position: absolute;
    background: white;
    width: 50px;
    height: 125px;
    opacity: 20%;

In the final effect, what flashed by was an inclined rectangle; So we add a transform: rotate (- 45DEG); style

button:after {
    transform: rotate(-45deg);

Use the top and left attributes to control the position of the rectangle

button:after {
    top: -2px;
    left: -1px;

Finally, the animation effect of button hovering and flashing is realized

Because it is hovering effect, you need to use: hover selector; We want to set the position of the rectangle when the mouse hovers

button:hover:after {
  left: 120%;

This sudden change of position is not the effect we want. We can use the transition attribute to add a transition effect, because this attribute is a new attribute of CSS3. We need to add a prefix to be compatible with other browsers

button:hover:after {
  left: 120%;
  transition: all 600ms cubic-bezier(0.3, 1, 0.2, 1);
   -webkit-transition: all 600ms cubic-bezier(0.3, 1, 0.2, 1);

It’s roughly realized. Let’s decorate it.

If you only want to display a rectangular overlay within the range of the button, you can add an overflow: hidden to the button label; style

button {
  overflow: hidden;

It can be seen that there are still some problems with the position of the overlay. In the final effect, the overlay is not displayed at first. We use the top attribute and the left attribute to adjust it

button:after {
    top: -36px;
    left: -100px;
