4 ways to hide layers in css

In front-end development, in order to achieve better user experience and page interaction effects, we often need to use hidden layer functions. Here, I will introduce how to use CSS to implement hidden layers.

In CSS, there are several methods of hiding layers as follows:

1. Display none

In CSS, the display or hiding of elements can be controlled through the display attribute. Among them, display:none is the simplest hiding method. It will completely hide the element, making it invisible and unable to respond to mouse events. For example:

.hide {display: none;}

This CSS code can hide the element with the class name "hide".

2. Visual hiding: transparency is 0

Another common hiding method is to set the element transparency to 0 through the opacity attribute. Elements hidden in this way also occupy layout space and can respond to mouse events. For example:

.hide {opacity: 0;}

This CSS code can make an element with a transparency of 0 appear invisible, but it still exists on the page, occupies the layout space, and can respond to mouse events.

3. Visual hiding: height/width is 0

Another way to hide is to set the height or width of the element to 0. This method can retain the layout space occupied by the element, but it cannot respond to mouse events. For example:

.hide {height: 0; width: 0;}

This CSS code can set the height and width of the element to 0 to achieve the hidden effect. Unlike the opacity method, the layout space occupied by the element is retained.

4. Visual hiding: CSS3 scale(0,0)

In CSS3, there is another way to hide the element by using scale(0,0) to scale the element to 0, thus Achieve hiding effect. Compared with height and width, elements hidden in scale mode can respond to mouse events, but this method is not supported in some old browsers. For example:

.hide {transform: scale(0,0);}

This CSS code can scale the element to 0 to achieve the hidden effect.
