Exclude Image Gallery from UL customization

Dear GP Team,

I have customized my bullet list with the code below. However, I'd like to exclude it from applying to the Wordpress Gallery image.

Here is my code:

.entry-content ul > li:before {
    background-color: #f56f46;
    border-radius: 2px;
    content: '';
    height: 9px;
    position: absolute;
    top: 15px;
    left: 0;
    width: 9px;
}

Thank you for your help.
