How to create a small CSS parser in JS?

Question

css

Here is the problem: there is a CSS code, for example

a {
color: red;
}
b {
background: green;
}

How using JS and regular expressions is it possible to break the code into blocks and put them in an array like this:
array[0] = ['a', 'color: red;' ];
array[1] = ['b', 'background: green;' ];
I’m not strong in regular expressions, therefore I’m not sure that this should be done with their help, please tell me the solution to the problem
