Is This CSS Syntax Correct?
css: the meaning of * mark
What is the function of * in CSS? I came across some code here that included it:
.center-wrapper{
text-align: center;
}
.center-wrapper * {
margin: 0 auto;
}
Could this be a mistake?
* represents the entirety of something.
Here, it signifies all elements within the .center-wrapper class.
It serves as a wildcard, matching all elements. For example in your case, it targets every element that is a descendant of elements with the "center-wrapper" class.
As per the official W3C documentation, this is known as a "universal selector", you can refer to http://www.w3.org/TR/css3-selectors/#universal-selector:
The universal selector, written as a CSS qualified name [CSS3NAMESPACE] with an asterisk (* U+002A) representing the local name, stands for the qualified name of any element type.
For instance, .main-container * denotes all content beneath each element with main-container class.
The symbol * represents the Universal selector.
When using .center-wrapper *, it targets all elements that are descendants of .center-wrapper.
* represents that the specified styles should be implemented throughout the entire webpage. This is intentional and not an error.
This signifies that it is going to target all elements located in that specific section of the DOM.
