CSS :only-child selector selects every element that is the only child of its parent. It means that it will select only those elements which have no siblings.
For example, if you use p:only-child, it will select every <p> element that is the only child of its parent.
Here is an example:
Example:
p:only-child{
background-color: yellow;
}
Here is another example which selects all <li> elements that are the only child of their parent element. This parent element can be a <ul> or an <ol>.
Example:
li:only-child{
background-color: yellow;
}
