Portfolio items don’t show using Internet Explorer

Kalium theme is not officially compatible with Internet Explorer browser because it is relatively an old browser (last release in 2013) and it doesn’t support the latest technologies such as CSS3, HTML5 and other. We have mentioned this in the theme item page but some users have reported experiencing a strange problem while using Internet Explorer and since we do not support the browser globally we have added a quick fix which will prevent the problem from occurring again.

Using the Internet Explorer browser, while switching the portfolio categories filter some of the portfolio items disappear, to fix this problem you will have to add this CSS to the Custom CSS area of your site (follow this guide to add custom CSS to your site).

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
   .portfolio-item .image-placeholder>img {
        opacity: 1 !important;
