How to use CSS to achieve button click effects

Foreword:
In modern web design, buttons are one of the indispensable elements in page interaction. A good button style can not only improve the user experience, but also enhance the visual effect of the page. This article will introduce a method of using CSS to achieve button click effects, adding dynamics and interactivity to the page.

1. Basic button style
Before realizing the button click effect, you need to define the basic button style first. You can use CSS pseudo-class selectors to define styles for buttons. Commonly used pseudo-classes include :hover and :focus.

Sample code:

.button {
  padding: 10px 20px;
  background-color: #2196f3;
  color: white;
  border: none;
  border-radius: 5px;
  cursor: pointer;
}

.button:hover {
  background-color: #0d8bf2;
}

.button:focus {
  outline: none;
  box-shadow: 0 0 5px #0d8bf2;
}

Analysis:

1. defines a class selector named .button, which represents the style of the button.
2. Set the padding, background color, font color, border and other properties of the button.
3. Use the :hover pseudo-class to define the button style when the mouse is hovering, and you can change the background color of the button.
4. Use the :focus pseudo-class to define the style when the button gets focus, and you can add borders and shadow effects.

2. Click effect
The click effect of the button can be achieved using the CSS pseudo-class selector: active. The :active pseudo-class takes effect when the button is pressed.

Sample code:

.button:active {
  background-color: #0b6de1;
  transform: translateY(2px);
}

Analysis:

1. Add: active pseudo-class after the .button class selector to indicate the style of the button when it is pressed.
2. Modify the background color of the button so that the button looks like it is pressed.
3. Use the transform attribute to achieve the effect of moving the button down by 2 pixels.

3. Complete code example

}

  background-color: #0b6de1;
  transform: translateY(2px);
}

Analysis:
