If you directly set the width attribute to the style of the span tag, you will find that it has no effect. If display:block is set, the width attribute takes effect, but the span is now the same as the div. If display:inline-block is set, span is placed in the same row and the width property takes effect. Common values of the element display attribute: 1) block: The default value of the block object. Forces the object to be rendered as a block object, appending a newline after the object. 2) inline: The default value for inline objects. Forces the object to be rendered as an inline object, removing the lines from the object. 3) inline-block: Renders the object as an inline object, but the content of the object is rendered as a block object. Adjacent inline objects are rendered on the same line. 4) non: hidden object. Unlike the hidden value of the visibility property, no physical space is reserved for the hidden object. |
