div 与 span 的区别

The <span> tag has very similar properties to the <div> tag, in that it changes thestyle of the text it encloses. But without any style attributes, the <span> tag won't change the enclosed items at all.

The primary difference between the <span> and <div>tags is that <span> doesn't do any formatting of it's own. The<div> tag acts includes a paragraph break, because it is defininga logical division in the document. The <span> tag simply tellsthe browser to apply the style rules to whatever is within the<span>.
