To add text to your pagination buttons or to change their shape/size you need to use CSS which is available on our Agency plan. Custom CSS is added under Theme → UI Elements → Custom CSS.

Here's some example CSS to get you started:

.Pagination__btn.Pagination__btn--next:before {
    content: "Next";
    color: white;
    vertical-align: top;
}

.Pagination__btn.Pagination__btn--previous:before {
    content: "Back";
    color: white;
    vertical-align: top;
}

On Essentials and Pro, you can configure the pagination appearance to include numbers or a progress bar. To do this, go to Theme → UI Elements → Pagination Buttons and choose your preferred style.
