Mobile phones and tablets have many screen sizes and different widths, so it is best to use the percentage width to adapt to various screen widths of different sizes when writing CSS for mobile phones and tablets. This percentage size is not too difficult, but it is not too light work, if you are not proficient in CSS, it is best not to toss this piece first, and practice the basics well.

Adaptive is stretched in equal proportion to the size of the view, and the size of the screen may be affected. You need to calculate this relative distance according to your needs to do the adaptation.
