The result is the smallest rectangle which contains the entire element, with read-only left, top, right, bottom, x, y, width, and height properties describing the overall border-box in pixels. For example, if we tilt it to the right, the right side will appear farther away, so the length of the right side will get smaller.

You might notice no visual changes because the text is already white (thanks to the first gradient) and the background is already set to the main color (thanks to the second gradient).

For the sizes, both gradient need to have 0 width and twice the element height (0% 200%). It would be too long to detail each one but with what we have learned so far you can easily understand the code. When the counter reaches the updateRate, an update will be made. We can do a transition from background-size: 0 to background-size: 100%. I know, I know. Callbacks There are some callbacks sprinkled around the Class.
