The width of is relative to the font that is | being used, while the SIZE attribute takes pixel values. | | Compare this with the CSS1 [1] alternative: | | <BR STYLE="display: inline; width: 10px"> <!-- pixel units --> | <BR STYLE="display: inline; width: 10pt"> <!-- point units --> | <BR STYLE="display: inline; width: 10em"> <!-- ems, relative to font size --> | <BR STYLE="display: inline; width: 10%"> <!-- %, relative to parent | element's width --> | | | The first example is equivalent to a horizontal spacer. The other | examples show examples of other units that are supported in CSS1. I | believe graphics designers want all these units to be available. | | The "display: inline" part in the above examples is there because BR | is normally a block-level element. One can avoid this annoyance by | using an inline element, but then an end tag is required: | | <SPAN STYLE="width: 10px"></SPAN> | | | > b) | > <SPACER TYPE=VERTICAL SIZE=height> | > (behaves like an 'invisble <HR>') | | Again, the only units supported are pixels. Compare this with: | | <BR STYLE="width: 10px"> | <BR STYLE="width: 10pt"> | <BR STYLE="width: 10em"> | <BR STYLE="width: 10%"> | | > c) | > <SPACER TYPE=BLOCK WIDTH=width HEIGHT=height ALIGN=alignment> | > (behaves like an invisible image) | | Ditto: | | <BR STYLE="width: 10px; height: 10pt"> | | [1] http://www.w3.org/pub/WWW/Style/css | | Regards, | | -h&kon | | Hakon W Lie, W3C/INRIA, Sophia-Antipolis, France | http://www.w3.org/people/howcome howcome@w3.org | | |
