Answer 1

Just add justify-content: center; to your code:

.vertical-align {
    display: ms-flex;
    display: flex;
    align-items: center;
    justify-content: center;  
}

Answer 2

I guess it depends what you're trying to achieve here. align-items does so vertically. Where as justify-content does so horizontally.

See this example. I have given the <h3> height, to illustrate that it is centred vertically.
