nit: the hex comment isn't helpful. if you really need to know you can just
google it: https://www.google.com/search?q=rgb(66%2C%20133%2C%20244)%20to%20hex

This is mainly for grepping it later as our designers specify colors in hex.

   /* End padding must be greater than --paper-checkbox-label-spacing */
   -webkit-padding-end: 16px;
   max-width: 550px;
   padding-bottom: 20px;
 }
 
-#accept-button-text {
-  text-transform: uppercase;
-}
-
 .bottom-buttons {
   padding: 0 6px; /* = 8px - 2px back button border */
 }
 
 #eula-accept-button {
   -webkit-padding-end: 18px;
 }
