Shorthand for CSS Properties

If you want to set all values to be displayed, you should limit the use of shorthand property declarations as much as possible.
Common abuses:
Padding, margin, font, background, border, Border-radius "?? Isn't that what I used to do?

In most cases, we do not need to specify all values for the shorthand property declaration. For example, the heading element of HTML only needs to set the value of the top, bottom margin (margin), so if necessary, just overwrite the two values. Excessive use of shorthand attribute declarations can lead to code clutter and unnecessary overwriting of property values causing unintended side effects.
