Scalable Vector Graphics (SVG) is a standard for including vector graphics (drawings) into a HTML page.

HTML itself does not (and can not) guarantee how your page is rendered, for it is a device independent format. You can't be sure even that your page is rendered as text (braille browsers, voice synthesis, etc.)

So pure HTML is not the right choice for a fixed format output; on the other hand, SVG is a format for specifying graphics and compliant browsers (most if not all modern browsers) try to render it exactly as you specified.
