How to make links underline?

Question

css

Hello. Tell me, how in this online store http://gamma24.rf did the dotted underlining of links? I myself tried to figure it out, I climbed into the css, as far as I understood, this is given by the following code

text-decoration: none;
  border-bottom: 1px dotted #181617;
