2. Block-level elements and inline elements

Block-level elements (block elements) and inline elements/inline elements (inline elements) ) is a concept in CSS. Elements like e388a4556c0f65e1904146cc1a846bee94b3e26ee717c64999d7867364b1b4a3 and 4a249f0d628e2318394fd9b75b4636b1473f0a7621bec819994bb5020d29372a are often called block-level elements. This is because these elements appear as a block of content, a "block box". In contrast, elements such as 45a2772a6b6107b401db3c9b82c049c254bdf357c58b8a65c66d7c19c8e4d114 and 8e99a69fbe029cd4e2b854e244eab143128dba7a3a77be0113eb0bea6ea0a5d0 are called "inline elements" because their content appears on a single line, an "inline box."

The concepts of block-level elements and inline elements are not fixed, but relative. We can change the type of box generated using the element's display property. This means that you can make inline elements (such as 3499910bf9dac5ae3c52d5ede7383485 elements) behave like block-level elements by setting the display attribute to block; you can also make the generated elements become inline elements by setting display to inline; or even, We can set the display attribute to none so that the element has no box at all. In this case, the box and all its contents will no longer be displayed and will not occupy space in the document.

     <p id="dv1" style="display: block">
         我是一个块级元素。
     </p>
     <p id="dv2" style="display: inline">
         我是一个行内元素。
     </p>
     <p id="p3" style="display: none">
         我是不可见的
     </p>
