therock Somewhere along this crazy road I learned (often times the hard way) the most important things I can do is be authentic, trust my gut, be the hardest worker in the room, celebrate the mistakes, be a grateful man and always remember that it's nice to be important, but it's more important to be nice.

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.
