Difference between using a space and a ~ symbol

What is the difference between using a space

h1 label {
  background: tomato;
  color:white;
  padding: 5px;
}

and using the ~ symbol

h1 ~ label {
  background: tomato;
  color:white;
  padding: 5px;
}

in the css?

When you use space it means that all labels inside h1 element will be affected with added styles, while tilda ( ~ ) means that only labels after h1 element will be affected with style. This example of "h1 label {} " is not the best to show the difference but for example if you have

<p>blabla</p>
<span> batman </span>
<p> is red </p>

and you write css like this for example

span ~ p {
color: red;
}

only paragraph after span element will be affected with red color. Enjoy coding

A space is a descendant selector, the item on the right must be inside the item on the left.

A tilde ("~") is a sibling selector, the item on the right must share a common parent, and must follow the item on the left (but there may be other sibling elements in between).

There's also the plus sign (+), which is the adjacent sibling selector. It works like the general sibling selector except that there may not be any other elements in between.
