HTML Classes: Chose a writing convention

[rcass]

I noticed throughout the php files the writing of class names is not consistent.

Some times if is camel case

wild-spring-2018/themes/wav-theme/page-templates/about.php

Line 137 in d8717da

<section class="schoolOutreach">

and other times it is kebab case

wild-spring-2018/themes/wav-theme/page-templates/about.php

Line 175 in d8717da

<header class="entry-header">

Best practice is to chose on style of writing! A lot of the default styles use kebab styles, so I suggest using those just for the sake of consistency.
