For those who end up here, the following works, although the class ‘button’ is possibly very common, so not sure if it will remove something elsewhere. I don’t use the portfolio section, but it seems ok for the rest of the site.
It can be removed in two ways.
1. This will remove the button, but keeps a large space at the bottom of the site that the button nested in:
a.button { display: none; }
2. This will remove the p container that the button nests in and therefore the button also. This is the methos I used, but again, I’m hoping this class name is not used elsewhere.
