Multiple fonts with face attribute:
The face attribute of font tag ·is used to change font style of a segment of text. In face attribute, we can assign more than one font-name at a time within double quotes with comma. For example,
< font face = "Bookman old style!, Broadway!, Forte, Arial" >
Welcome to HTML
< /font >
Browser first tries to find out whether the font-name in the list is supported or not. If the first font is not supported by the browser, then it displays the text in second font, otherwise it will display next one. If no font in the list is supported, then the browser display the in the default font.

These tags may be shows the same output, but the usage of tags are varying. The following table shows the usage of this kind of tags.

While writing HTML document, we should use the appropriate tags according to its usage. If we want show a text as underlined use < u > instead of < ins >

The text what we see on browser cannot delete or insert. But we can show a text as deleted or inserted. < del > and < ins > tags are used to markup a segment of text as deleted or inserted respectively. These two tags are container tags. The text what we specify between < del > and < fdel > will be displayed as strike through. The text we specify between < ins > and < fins > will be shown as underlined.
