In CSS, the text-decoration property is used to control the decoration or styling of text within an HTML element. The text-decoration property can be applied to inline and inline-block elements. Values for the text-decoration property: none: This is the default value and removes all text decoration. underline: Adds an underline to the text. overline: Adds a line above the text. line-through: Adds a line through the text, like striking through it. blink: Creates a blinking or flashing effect for the text. This value is not widely supported and is often avoided due to its obtrusive nature.
