How In-Line Elements Are Mixed in Text Lines?

If an in-line element is mixed in a text line, it will be placed immediately after the preceding character. The vertical position of the in-line element will be determined by its vertical alignment style property, vertical-align, as shown in the following tutorial exercise:

<html><head>
<style type="text/css">
  H1 {font-size: 20px}
  DIV.page {width: 425px; border: 1px solid black}
  TABLE#out {background-color: #ffdddd}
  TD#box {border: 1px solid black}
  P#box {width: 300px; height: 300px; 
    font-size: 14px; 
    line-height: 30px;
    background-color: #ddddff}
  STRONG {font-size: 30px;
    line-height: 60px;
    background-color: #ffffff}
  EM {font-size: 30px;
    line-height: 60px;
    vertical-align: top;
    background-color: #ffffff}
  TD.legend#w30 {height: 30px; background-color: #ffffff}
  TD.legend#w60 {height: 60px; background-color: #ffffff}
  TD.legend#g30 {height: 30px; background-color: #dddddd}
  TD.legend#g60 {height: 60px; background-color: #dddddd}
</style>
</head><body><div class="page">
<H1>Text Paragraph with In-line Elements</H1>
<table id=out><tr>

Save this document as inLineElements.html, and view it with a browser, you will see that in-line elements are vertically aligned at the bottom. If the in-line element is a text string, its line-height specifies the full height including margins. See the following image for details:
           

How In-line Elements Affect Line Box Heights?

If a line box contains only text without any in-line elements, its height is equal to the line-height property of the enclosing block element.

If a line box contains text mixed with in-line elements, its height will be affected by heights of in-line elements and their vertical alignments. The new height will be the distance from the top of the highest in-line element to the bottom of the lowest in-line element.
