If we want to match elements that appear immediately after the first selector, we can use the adjacent sibling selector ( ). Here, both selectors are children of the same parent element.

The syntax of CSS adjacent sibling combinator is as follows:

Selector + Selector{
   attribute: /*value*/
}

If we want to select sibling elements under the same parent element, regardless of the position of the second selected element, we can use CSS Universal sibling selector.

The syntax of CSS universal sibling selector is as follows:

Selector ~ Selector{
   attribute: /*value*/
}

The following example demonstrates CSS adjacent and general sibling selector properties.
