add frame to thumbnails

Put in any css file:

.thumbnail-frame {
// Anything you like EXCEPT width, height and margins
// See also wp-photo-albums-plus/theme/wppa-style.css
// Do NOT modify the settings for: display, float and overflow
}

Also see https://wppa.opajaap.nl/customizing-wppa/modifying-css/

sir can u give me example coding. I am not so good in editing.

Sorry for asking silly questions. Help me, my thumbnail size is 240 and thumbframe width is 250. I want dark grey color frame. Plz give me coding and tell me where to put it.

Open file …wordpress/wp-content/plugins/wp-photo-album-plus/theme/wppa-style.css and find this:

/* Wrapper for thumbnail background */
.thumbnail-frame {
	float: left;
	background-color: transparent;
	display: inline;
	overflow: hidden;
	text-align: center;
}

You can change:

background-color: transparent;

into:

background-color: #333333;

to make the background dark grey.

If you copy the file to your theme directory, that copy will be used, so you can safely update wppa+ without losing your modifications.

Thank u very much sir…
