div css display and hide

CSS can control the visibility of elements through the display attribute. The following methods are commonly used:

1. display: none;
   Use display: none; to hide elements. When an element is set to display: none;, the element will not appear on the page and will not take up space.

For example, in the following code snippet, the div element is set to display: none;, so it will not be displayed on the page:

<div class="hidden">这是要隐藏的内容</div>

<style>
.hidden{
  display: none;
}
</style>

2. display: block;
   display: block; means displaying the element as a block-level element. By default, the div element is a block-level element and will be displayed on its own line on the page.

For example, in the following code snippet, the div element is set to display: block;, which will be displayed as a block-level element:

<div class="block">这是块级元素</div>

<style>
.block{
  display: block;
}
</style>

3. display: inline;
   display: inline; means displaying the element as an inline element. By default, the span element is an inline element and will be displayed on the same line as other inline elements or text on the page.

For example, in the following code snippet, the div element is set to display: inline;, which will be displayed as an inline element:

<div class="inline">这是行内元素</div>

<style>
.inline{
  display: inline;
}
</style>

4. display: inline-block;
   display: inline-block; means displaying the element as an inline block-level element. Inline block-level elements can be displayed on the same line as other elements like inline elements, and can also set width, height, inner and outer margins and other attributes like block-level elements.

For example, in the following code snippet, the div element is set to display: inline-block;, which will be displayed as an inline block-level element:

<div class="inline-block">这是行内块级元素</div>

<style>
.inline-block{
  display: inline-block;
}
</style>

Using the display attribute can easily Implement the display and hiding of elements. It should be noted that if an element is set to display: none;, all child elements under the element will also be hidden. Therefore, in practical applications, appropriate display attributes need to be selected according to specific needs.
