Changing the color of image borders

– Try using tool like Firefox with the Firebug add-on for this kind of CSS work. https://getfirebug.com/

I am already using Firebug. I am a newbie and I am learning CSS at the moment. But I cannot figure out what to do. Thanks!

img[class*="align"],
img[class*="wp-image-"],
#content .gallery .gallery-icon img {
	border-color: #006699;
}

You post CSS codes in the custom CSS box

Thanks. While waiting I created a new image class called “teamfotos” and added the following code with similar success:

img.teamfotos {
	border: 1px solid #006699;
	padding:1px;
	}

But in both cases I only create a border around my images. My aim is to change the bold light grey background around each image:

Thanks for help!

/* caption background color */
.wp-caption {
	background-color: blue;
}

/* caption text color */
.wp-caption p.wp-caption-text,
.wp-caption .wp-caption-text:before {
	color: red;
}

/* caption image border color */
.wp-caption img {
	border-color: pink;
}

Thanks!!!
