Display of CSS, hover, overflow, &copy (copyright symbol), Borer-radius (border fillet)

One, Display:none hidden block display

Visibility:hidden Hidden Visible Display

The values for both the Display:none and Visibility:hidden properties are hidden, but they are somewhat different from the hidden pair.

The difference between display and visibility is that the display hides the same element, and the visibility hides the position of the element, but the content is hidden.

Second, hover: is not a style, with the ID of the element or class, followed by a colon hover, representing the mouse on this element to show which styles

For example:

Third, overflow
