Margins
You can add a margin using the "margin-left", "margin-right", etc. properties. For example, this style would give all paragraphs a left margin of 100 pixels.
P
{
margin-left: 100px;
}
Line spacing
You can control line spacing with "line-height":
P
{
line-height: 30px;
}
Width
You can control the width of a block (inside its margins) using the "width" property. This works best with <div> tags (see next page).
DIV.main
{
width: 400px;
}
