= Pseudo-classes ::first-line =

The ::first-line pseudo-element describes the contents of the first formatted line of an element.

== Syntax ==
<pre>
selector::first-line{ preperties }
</pre>


== Point, Note ==
*Note that the length of the first line depends on a number of factors, including the width of the page, the font size, etc.
*In CSS, the ::first-line pseudo-element can only have an effect when attached to a block-like container such as a block box, inline-block, table-caption, or table-cell.
*The ::first-line pseudo-element is similar to an inline-level element, but with certain restrictions. The following CSS properties apply to a ::first-line pseudo-element: 
**font properties
**color property
**background properties
**‘word-spacing’
**‘letter-spacing’
**‘text-decoration’
**‘vertical-align’
**‘text-transform’
**‘line-height’


== Example ==
[style.css]
  p:first-line{
    text-transform: uppercase;
  }
