How to Add Zoom in and Out Image on Hover Effect on All Post

Hi,

Unfortunately this can be done only with custom work.
If you want you can try this custom css
.td-module-thumb:hover img{
-ms-transform: scale(1.1); /* IE 9 */
-webkit-transform: scale(1.1); /* Safari 3-8 */
transform: scale(1.1);
transition: transform .3s;
}
.td-module-thumb img{
transition: transform .3s;
}

Thank you for your understanding.
