what is the difference between div and span tags

DIV TAG:

Following are the characteristics:

1. As the name indicates, the div tag defines a ‘division’ in a web page.
2. div is a block-element; its default display value is “block”.
3. div tag is commonly used while creating Css based layouts in html.
4. by default, a line-break is placed before and after this element.

SPAN TAG:

Following are the characteristics:

1. span tag makes no visual difference in the page, unless customised with style attribute.
2. span is an in-line element.
3. span is commonly used to stylize texts. The in-line feature makes it easy to use custom styles without changing the layout.
4. No line-breaks by default, but this can be achieved if we change its in-line nature by specifying in the style attribute to ‘display:block;’
