Definition outline
Подработка: Перевод страницы
An outline is a line that is drawn around elements, outside the borders, to make the element "stand out".
The outline property is a shorthand property for:
- outline-width
- outline-style (required)
- outline-color
If outline-color is omitted, the color applied will be the color of the text.
Note: Outlines differ from borders! Unlike border, the outline is drawn outside the element's border, and may overlap other content. Also, the outline is NOT a part of the element's dimensions; the element's total width and height is not affected by the width of the outline.
