CSS
Margins
Using
CSS (Cascading Style Sheets) has become a popular way to
simplify the programming of many style elements, such as color,
font, alignment, tables, spacing, and margins. CSS margins
refers to the spacing that is around webpage elements, at the
top, bottom, and sides of pages and how that spacing is used to
apply properties to the borders of any HTML document.
Previously, HTML code required repetitive entry of code
elements and resulted in more complicated page
programming.
Each of
the CSS margins can be changed independently, allowing the page
to be fully customized with different layouts. Values are used
to describe the margins, and are typically written as
"margin-top," "margin-right," "margin-bottom," or
"margin-left." Values are assigned to the CSS margins either as
one value that applies to each margin, or individually as
percentages. For example, CSS margins code may look like,
"
" and
this will result in a document having a border of 20 pixels
on each side. By changing the "20," the length, width, or
height of the margin is adjusted.
Changing
the border is not difficult, and each side of the document can
have its own properties, the CSS margins would just be coded to
incorporate those instructions.
