Spaces between html attributes and values?

Are they allowed? and do they work with all browsers?

Example:

<div role = "region"
     id = "some-id"
     class = "a-class another-class">
Solution

  • Yes, any amount of whitespace is allowed and will work in all browsers.

    From the Attributes section of the HTML5 living standard on unquoted, single-, and double-quoted attribute value syntax:

    The attribute name, followed by zero or more ASCII whitespace, followed by a single U+003D EQUALS SIGN character, followed by zero or more ASCII whitespace, [...]

    One consideration - this will add to the page size, so if bandwidth and performance are concerns, try to limit the amount of whitespace you use.
