:link pseudo class selector in CSS

The :link selector is a pseudo-class that targets all unvisited anchor (a) elements on a page.

When used in combination with the :hover, :link must be used first, or else not be defined at all, in order for the :hover styles to work. This is because they are equally specific, so if :link came after, those styles would override the hover styles.

The :link pseudo-class will target all anchor elements that have an href attribute, even if the href has an empty value.

:last-child pseudo class selector in CSS

The :last-child selector allows you to target the last element directly inside its containing element.

It is used to style content based on its relationship with parent and sibling content.

Using :last-child is similar to :last-of-type but with one important difference: it is less specific. :last-child will only try to match the very last child of a parent element, while last-of-type will match the last occurrence of a specified element.

:lang() pseudo class selector in CSS

Language in HTML, is determined by a combination of the lang=”” attribute, the meta element, and by information from the protocol such as the HTTP Accept-Language request-header field.
