[resolved] Response Message Shows Twice

This problem was reported in a previous theme, but a moderator closed the thread (and obnoxiously demanded that two responders who were providing useful information cease posting on that thread):

In any case, here is the issue, and solution, it has to do with screen-reader CSS. Some themes do not provide the required support for screen reader text so it shows up in cases it shouldn’t. Here is the css to add in order to take care of that issue:

.screen-reader-response {
clip: rect(1px, 1px, 1px, 1px);
position: absolute !important;
height: 1px;
width: 1px;
overflow: hidden;
}
.screen-reader-response:focus {
clip: auto !important;
display: block;
height: auto;
left: 5px;
top: 5px;
width: auto;
z-index: 100000; /* Above WP toolbar. */
}
