Where is '~' used in CSS ?

#css #beginners #programming #webdev

If we rank the popularity of the CSS combinators, tilde is probably at the bottom of the list. It is a nifty little combinator written for niche situations!

Let's take a step back and get to know the CSS combinators :

Ranking CSS Combinators :

1." " : Descendant combinator

The most popular CSS combinator is the descendant combinator.

Confused what " " does ? Here's the syntax :

.card-container button-container{
     /* some property here */
}

As a Front-end Developer , you end up using this operator without realizing that you are using it ! What it does, is selects the second element only if the first element is one of its ancestors.

You can play around with the code here for better understanding : code sample

2.> : Child combinator

In a close second is the child combinator , and it's job is to select the second element only if it is the direct child element of the first element.

Examples will clear your confusion :

card-container > p{
     /* some property here  */
}

Here's a code sample similar to the code sample above : code sample

3.+ : Adjacent sibling combinator

In my coding journey I haven't had the chance to use the last two on our ranking list in my projects yet , but here goes !
The plus , or the adjacent sibling combinator , is used to select the adjacent element of first element , if it matches with the second element.

Example :

h1 + p{
   /* some property here */
}

Here's a code snippet to help you understand better : code sample

4.~ : General sibling combinator

Last but certainly not the least , is tilde. Known technically as the general sibling combinator . Or worm . Or squiggly line. Whatever you wanna call it , it's job is to select any siblings of the first element , which match the second element.

Here's how :
