Someone please help...I'm using Coraline theme and I managed to change the opacity of the content-container so it looks decent with my background. The problem is that images and videos are too close to the margins of the content-container and makes the post look a bit strange. Below is the code from css style sheet I'm currently using and wanted to know what I need to do to fix these margins for the posts content. Thanks in advance.

#container {
clear: both;
margin: 0 auto;
opacity: 0.978;
}
#content-container {
width: 100%;
background: #E5E5E5
}
