DNN 4.5.5

I want to make all Text/HTML hyperlinks appear by default as 'underline' (the default hover state) even when there is no mouse over.

I update the following selector in this way (Admin > Host Settings > Stylesheet Editor):

A:link  {
    text-decoration:    underline;
    color:  #003366;
}

After I 'Save Style Sheet' and 'Refresh', only some of the Text/HTML hyperlinks appear with the underline; others do not.

In one Text/HTML module instance with a simple horizontal list of hyperlinks with 4 items, 2 links appear with underline, 2 do not.

In a User Defined Table instance with many records, most of the column type URL hyperlinks appear with underline, but some do not.

Has anyone seen this behavior? Am I NOT setting the A:link selector correctly?

I thought Admin > Site Settings > Stylesheet Editor (portal.css) would be the right place to override default.css, module.css, skin.css, etc. But is it the other way around? I'll hunt down the CSS line and see what I find, Sebastian - thank you.

I just discovered one thing: I need to override all four hyperlink classes/selectors in Stylesheet Editor, THEN all hyperlinks appear as underlined. The state of some hyperlinks was setting text-decoration: none;

A:link  {
    text-decoration:    underline;
    color:  #003366;
}

A:visited   {
    text-decoration:    underline;
    color:  #003366;
}

A:hover {
    text-decoration:    underline;
    color:  #ff0000;
}

A:active    {
    text-decoration:    underline;
    color:  #003366;
}
