8.4.3. Managing the Line Height of Inline Elements

In the previous section, we had a fewcases where changing the line-height of an inlineelement led to the possibility of text from one line overlappinganother. In each case, though, the changes were made on individualelements. So how can we affect the line-height of

Figure 9-22. Another approach to defining a "change bar"

Remember when we mentioned static-position muchearlier in the chapter? Here's one example of how it works andhow it can be very useful.

Another important point is that when an element is positioned, itestablishes a containing block for its descendantelements. For example, we could absolutely position an element andthen absolutely position one of its children, as shown in Figure 9-23.

right padding, they will be visible, as Figure 7-60 makes apparent.

Figure 7-60. Padding on an inline element

Note the extra background space that appears on either end of the boldfaced text. There's your padding.

This all seems familiar enough, even when the boldfaced text stretches across multiple lines. Turn to Figure 7-61 margins, borders, and padding; styles can be applied within them, just as with any other element. This can make them very useful for the creation of sidebars, "sticky notes," and other such effects. One example is the ability to set a "change marker" on any paragraph that has been edited. This could be done using the following styles and markup:

SPAN.change {position: absolute; top: 0; left: -5em; width: 4em;
font-weight: bold;}

DIV {width: 400px;}
P {text-indent: 5%;}
<P>This paragraph is contained inside a DIV which is 400px wide, so the
first line of the paragraph is indented 20px (400 * 5% = 20).  This is because
percentages are computed with respect to the width of the parent element.</P>

Note that this indentation will only apply to the first line of an element, even if you insert line breaks. Thus, as Figure 4-8 shows:
