Formatting test questions

I think we can resize this easily enough but replacing the ) with a . would be the obstacle.

In my platform - it looked as though it was at a 14 for font-size already.

I personally thought a bump to 16 was not much of a distinction so I went with 18 and
increased the font-weight to 700 but you can tinker however you desire.

/** Modify the numbering system for quiz questions **/
/** Adjust values as desired **/

.question-block .numbering {
    font-weight: 700;
    font-size: 18px;
}
