The <spacer> HTML element is an obsolete HTML element which allowed insertion of empty spaces on pages. It was devised by Netscape to accomplish the same effect as a single-pixel layout image, which was something web designers used to use to add white spaces to web pages without actually using an image. However, <spacer> is no longer supported by any major browser and the same effects can now be achieved using simple CSS.

Firefox, which is the descendant of Netscape's browsers, removed support for <spacer> in version 4.


Like all other HTML elements, this element supports the global attributes.


This attribute determines type of spacer. Possible values are horizontal, vertical and block.


This attribute can be used for defining size of spacer in pixels when type is horizontal or vertical.


This attribute can be used for defining width of spacer in pixels when type is block.


This attribute can be used for defining height of spacer in pixels when type is block.


This attribute determines alignment of spacer. Possible values are left, right and center.
