Summary: A search box mainly has three parts, one is the input box part (the left one), the other is the search button part (the right one), and there is a large div that contains them;

1. First set the width, height and border color of the large div. This should be calculated in advance according to personal needs.

2. Float the input (input box part) to the left and the button (button part) to the right. Remember to use overflow: hidden; attribute for large divs;

3. Adjust the height and width of the input. Remember to use padding to prop up its height value, so that it does not stick to the border when inputting fonts, which increases the beauty; for the width value, you can add a little padding value on the left side for the sake of beauty.
