Browsers make placeholders semi-transparent. Sometimes it can be inconsistent with WCAG 1.4.3. It’s possible to override it using custom CSS. Below is some sample code that makes placeholders more visible.
.dgwt-wcas-sf-wrapp input[type="search"].dgwt-wcas-search-input::placeholder { opacity: 0.8!important; color:black!important } .dgwt-wcas-sf-wrapp input[type="search"].dgwt-wcas-search-input::-webkit-input-placeholder { opacity: 0.8!important; color:black!important } .dgwt-wcas-sf-wrapp input[type="search"].dgwt-wcas-search-input:-moz-placeholder { opacity: 0.8!important; color:black!important } .dgwt-wcas-sf-wrapp input[type="search"].dgwt-wcas-search-input::-moz-placeholder { opacity: 0.8!important; color:black!important } .dgwt-wcas-sf-wrapp input[type="search"].dgwt-wcas-search-input:-ms-input-placeholder { opacity: 0.8!important; color:black!important }
