The margin property doesn't work, what's the problem?

Question

css

.sidebar {
  float: right;
  width: 222px;
  padding: 25%
  margin: 0 0 16px 0;
  border: solid 5px #f2f2f2;
  border-radius: 5px;
  background-color: #f9f9f9;
  margin: 0 0 16px 0;

The essence of the problem is that the first one marginis italicized and does not work.
I decided to write another one and it works, it doesn't stand out in italics. When trying to delete the first one, the border was highlighted in italics and also stopped working.
How to get rid of this epidemic?

Answer 1

Semicolon forgotten after padding
