content column

elements can appear to be wider than their parents through negative margins, floated elements can appear to protrude out of their parents.

Let's consider once again a floated image which is floated to the left, and which has left and top margins of -15px . This image is placed inside a DIV which has no padding, borders, or margins. The result will be as shown in Figure 8-42.

All templates are XHTML 1.0 and CSS2/ tableless.

TIP

In practice, browsers come with pre-assigned styles for manyelements, and margins are no exception. For example, in CSS-enabledbrowsers, the "blank line" above and below each paragraphelement is generated using margins. Therefore, if you don'tdeclare margins for the P element, the browser mayapply some margins on its own -- which is to say that just becauseyou don't declare margins for an element doesn't meanthat there won't be any. "blank" space around the paragraphs is actually theirmargins. (If the DIV had any padding, there wouldbe even more blank space, but that wasn't the case here.)

In a similar fashion, the overall width of a list item's element box is equal tothe content width of the list element that contains it. As you cansee in Figure 8-8, the margins of a parent elementcan influence the layout of a child element.

will simply substitute some other font, and the effect you want may bediminished or lost.  The <BASEFONT> or <FONT>tags can list multiple fonts in order of preference.  The list shouldinclude a generic font family as a last resort, e.g.
   <FONT FACE="Creepy, Times New Roman, serif">
Generic font families include serif, sans-serif, monospace,cursiveand fantasy

Note that as of HTML 4, you are encouraged to use style sheets insteadof these in-line font manipulations, but these tags work fine.
