When we want to select an element, we need to identify which one we're looking for. This is where the selector comes in - it's like a superpower that lets us pick the right element from the crowd.
Let's say we have a bunch of buttons with different classes, like:
{{button { background-color: red; }}} button { background-color: blue; }}} button { background-color: green; }}}
How do we select the red one? We use a selector like this: <button { background-color: red; }
But what if we have multiple buttons with different styles? Like this:
{{button { background-color: red; }}} button { background-color: green; }}} button { background-color: blue; }}}
Then we use a more specific selector like <button { background-color: red !important; } or {{button { background-color: red; }}} button { background-color: blue; }}} button { background-color: green; }}} button { background-color: red !important; }
This is where we use the ~ selector, like this: <button { background-color: green; } ~ <button { background-color: blue; }
And that's it! Now we've selected the right button with the red background color.
