Selecting Elements without Parent Knowledge: nth-Child and First/Last-Child Selectors
In certain scenarios, it becomes necessary to select specific child elements within a webpage without knowing the exact parent element. CSS provides several selectors to address this need, including nth-child, first-child, and last-child.
Using nth-child Selector
The nth-child selector enables you to target specific child elements based on their position within their siblings. For instance, .select-me:nth-child(2) will select the second .select-me element within any parent, regardless of its name or type.
Absence of :first and :last Selectors
Unlike nth-child, CSS does not provide direct :first and :last selectors that function on any element. This is because every HTML element (apart from the root element) has a parent. Hence, specifying first-child or last-child is sufficient to select the desired element, even without knowing the parent.
