gravity forms plugin - Icon should appear when button selected (via HTML) -

currently when button selected, font goes "bold" , dot appears in spot.

i'd make small icon (a tick) appear also/instead. or i'm open other ideas.

i'm using gravityform. here site click here. i'm talking button next text "icon appear". here screenshot

requirement: icon appear next button when has been selected/clicked.

is there simple way html achieve this?

use below code :

label > img {display: none;} input[type=radio]:checked + label > img{display:inline-block;} 

for prevent global impact, use classes / ids accordingly like...

#section label > img {display: none;} #section input[type=radio]:checked + label > img{display:inline-block;}
