How to Button a Rules Link URL
After study, I used the above css with a 'btn btn-primary btn-block' in the Other of my View (where the Rule itself goes) in the CSS information properties.  It for now gave me a working button, but it does need some further CSS, but I have my answer.

Additionally, I added :

/* Rules Link Post unvisited link */
.rules-link-post-classified
a:link {
    color: #FFFFFF;
}
a:hover {
    text-decoration: none;
}
a:active {
    text-decoration: none;
}


into my theme.css (using currently the Tweme Bootstrap).
As I wanted white text on a blue button, and then I used the above css with a 'btn btn-primary btn-block' in the other of my View in the CSS information properties.

Furthermore, I didn't want the 'hover' underline to show on the link when the user moved over it to click, so I used the text-decoration as 'none' to remove it under the 'a:hover' with 'a:active' elements above.
BINGO!

There maybe more functional CSS ways in the file.css, but hey we're learning!
