I was able to use this hack: How can I replace text with CSS? --to replace a closing 'X' button on a lightbox from a third party library I'm using. It works great in all browsers but IE11. It seems IE hides both the element and the pseudo-element even though visibility: visible is set on the pseudo. If I toggle visibility using dev tools, they both show up.
Note: if the actual 'X' button were an actual 'X' character, I could easily style it as needed. Unfortunately, they use a symbol, so I have to resort to using this method to "replace" it with an actual X, to match the design standards of the site.
CSS for the button:
/* Hack to replace the close button text */
#_pendo-close-guide_ {
visibility: hidden;
}
#_pendo-close-guide_:after {
content:'X';
visibility: visible;
display: block;
position: absolute;
right: 6px;
top: 8px;
font-size: 17px;
font-weight: 200 !important;
font-family: 'Open Sans', 'Helvetica Neue', Helvetica, sans-serif;
color: #444;
}
Any help would be much appreciated.
