Hi!
The only way to change that right now is via custom CSS:
.asp_shortcodes_container * {
font-weight: 300 !important;
}
.asp_shortcodes_container input::-webkit-input-placeholder { /* Edge */
font-weight: 300 !important;
}
.asp_shortcodes_container input:-ms-input-placeholder { /* Internet Explorer 10-11 */
font-weight: 300 !important;
}
.asp_shortcodes_container input::placeholder {
font-weight: 300 !important;
}This will force a 300 weight on all of the elements. Please note, that you cannot combine these rules into a single one, because placeholder styles are only rendered in browsers if they are separated.
