In this snippet, we’re going to animate the progress bar created with the HTML <progress> tag. In our example, we style Shadow DOM elements, but one thing that may cause difficulties is animating the background which is represented as a repeating linear-gradient.
To delay an animation, we use the CSS animation-delay property, which specifies the time between an element being loaded and the start of an animation. But there can be some difficulties when delaying the animation, such as the problem when an element disappears after the animation. Let’s see the solution to this.
First of all, we must understand that there isn’t any best option of measurement unit for all cases, and that’s why this question is mostly opinion-based. But let’s discuss each of the units.
CSS defines a reference pixel that measures the pixel size on a 96dpi display. On display with a dpi significantly different from 96dpi, the user agent will rescale the px unit so that its size will match the one of a reference pixel.
