When I realized that, no individual step is hard in any process. Building this airport I'm standing in right now started with a guy writing the architectural plans on paper. That's not hard for him to do. Then laying the first beam isn't had. The whole thing is really hard. So, just take each step kind of piece by piece and when I was able to do that and stop trying to chase this prize and started putting in the work, things just started coming together.

contain

The contain CSS property allows an author to indicate that an element and its contents are, as much as possible, independent of the rest of the document tree. This allows the browser to recalculate layout, style, paint, size, or any combination of them for a limited area of the DOM and not the entire page, leading to obvious performance benefits.
