Grey border around my ping images. Need to remove

Hey All, I amde some social media buttons and when I upload them they have grey borders.

I know I can use the

img { border: none;} in my css, but I have other images I need to use a border on.

I tried this in my CSS code but it still is showing.

#social {
	float: right;
	margin-top: 10px;
	margin-right: 100px;
	margin-bottom: 0;
	margin-left: 0px;
}

.social img {
	border: none;
	}

Any ideas what I can do to remove the border, and space out the images?

#social img {
border: none;
padding: 5px;
}

Worked perfectly. Just needed to change the . to #

Very much appreciated.
