What are the differences between inline elements and block-level elements in html?

This time I will bring you the what are the differences between html's inline elements and block-level elements, what are the precautions when using html's inline elements and block-level elements, The following is a practical case, let’s take a look.

html tags are divided into two types, inline elements and block-level elements. First, let’s understand the concepts of inline elements and block-level elements:

Block-level Element: Generally a container for other elements, it can accommodate inline elements and other block-level elements. Block-level elements exclude other elements located on the same line as them. The width (width) and height (height) attributes can be set. Block-level elements in normal flow Will be placed vertically. Common block elements are "div"

Inline elements (inline elements): Inline elements can only accommodate text or other inline elements. They are descendants of block-level elements, which allow other inline elements to be located with them. On the same line, the height (height) and width (width) cannot be set. A common inline element is "a".

According to the concept of block-level elements, we can understand that block-level elements have line breaks before and after them, which is equivalent to adding a 0c6dc11e160d3b678d68754cc175188a tag before and after the element. We can think of block-level elements as a block or a rectangle, so block-level elements can set the height and width attributes

Example:
css file:

#div1{  
 width:200px;  
 height:200px;  
 background:#666  
 }  
div2{  
 width:200px;  
 height:200px;  
 background:#F00  
 }

html file:

<div id="div1">  
     div1  
块级元素排斥其他元素与其位于同一行  
</div>  
  <div id="div2">  
     div2  
块级元素排斥其他元素与其位于同一行  
</div>

Two div elements are not located on the same line

According to the concept of inline elements, we can understand that there are no line breaks before and after inline elements. We can think of an inline element as a line, so it cannot set the height and width attributes.
