Customising the Quote Block and Tagline

Hello.

I was wondering is there a code for the quote block and author to be in a box frame and text color changed? I found this code but it only contains the quote and changes the color of that text, not the author.

blockquote {
    width: 90%;
    border-color: #ef420d;
    border-width: 5px 5px 5px 5px;
    border-style: solid solid solid solid;
    padding: 5px 5px 5px 5px;
    background-color: #eee;
}

Another customization question I have:

Is there a code that will make the entire tagline area not just the text clickable?

Thank you :)
