Sure, you can style those elements differently. One easy way to do so is to copy some of the CSS from the plugin’s stylesheet into your theme’s stylesheet. The block you want is in the file wp-customer-reviews.css in the plugin directory, starting with #wpcr_button_1 — you’ll need to play with the different styles to make the button bigger. One simple change might be just use font-weight:bold !important; (instead of font-weight normal) and font-size: 20px !important; (instead of 13).
You could make these changes directly in the plugin’s CSS file but they could be overwritten if/when the plugin is updated.
Hi thanks for this. I’ll make the changes but I’ll do them in a child theme. Thanks again for your help.
