The greater than symbol (">") in css represents the unique sub-element selector of css3 (element>element) . Child selectors can only select elements that are children of an element.
If you do not want to select any descendant elements, but want to narrow the scope and select only the child elements of a certain element, please use the child selector (Child selector).
For example, if you want to select only strong elements that are children of the h1 element, you can write:
h1 > strong {color:red;}
This rule will turn the two strong elements below the first h1 red , but the strong in the second h1 is not affected:

css child element selector
element>element selector is used to select a specific parent element.
Note: If the element is not selected, you cannot directly specify the child element of the parent.
The sub-selector uses the greater than sign (sub-combination symbol).
Subconjuncts can have whitespace characters on both sides, which is optional. Therefore, there is no problem with the following writing:
h1 > strong h1> strong h1 >strong h1>strong
If read from right to left, the selector h1 > strong can be interpreted as "select all strong elements that are children of the h1 element".
