css

The people who used spinCSS, who knows how to highlight the entire window, namely the tag body?

Answer 1

To get the styles of all elements on the page, you need to iterate over these elements in a loop and request styles for each separately:

document.querySelectorAll('*').forEach(function(elem) {
    style = getComputedStyle(elem);
    console.log(style);
});

Further, already assembled styles can be processed as you like.
