Try using Firefox with the Firebug add-on for this kind of CSS troubleshooting. Or use whatever developer tool is available in your web browser.
I’m editing the original
.yarpp-thumbnails-horizontal .yarpp-thumbnail {
border:1px solid rgba(127, 127, 127, 0.0980392);
height:170px;
margin:5px 5px 5px 0;
vertical-align:top;
width:130px;
}
to
.yarpp-thumbnails-horizontal .yarpp-thumbnail {
height:170px;
margin:5px 5px 5px 0;
vertical-align:top;
width:130px;
}
but nothing happen
Are you making the changes directly on the styles-thumbnails.php on the style.css or on the style.css of a child theme?
I have noticed in the last 48 hours that style.css within the child theme are not been picked up by the browsers first. Instead the parent style within the PHP is been picked up. if you are making changes directly on the plugin these may become obsolete on any new upgrades.
Like @magnusccd said, you’ll want to make sure the changes are made to your own theme’s CSS, not within the plugin. If you’re having trouble getting the custom CSS to be read by browsers, try adding the !important declaration to those CSS declarations.
