Custom styles
Perhaps you want something more than just changing the layout of the search form. In this case you can use custom css rules to customize search form in any way that you need.
Example: lets change search form border and submit button color and make rounded borders. In this case you can use following css:
.aws-container .aws-search-form .aws-form-btn {
background: #fff;
border-color: #4498c6;
}
.aws-container .aws-search-form .aws-search-btn.aws-form-btn {
background: #4498c6;
}
.aws-container .aws-search-form .aws-search-btn svg {
fill: #fff;
}
.aws-container .aws-search-field {
border-right: none !important;
border-color: #4498c6;
}
.aws-container .aws-search-form .aws-main-filter.aws-form-btn {
border-left: none !important;
}
.aws-container .aws-search-field {
border-top-left-radius: 10px !important;
border-bottom-left-radius: 10px !important;
}
.aws-container .aws-search-form .aws-search-btn.aws-form-btn {
border-top-right-radius: 10px !important;
