Add CSS class to Div

I have the Inline Related Plugin installed.

The divs holding the links have dynamic CSS added to them and that makes it difficult for you to style them through Additional CSS.

I would like to automatically add a CSS class to the div holding the links in addition to the one the plugin outputs.

See the CSS output it has currently.

the Div

.sa03dbe163e71ee0412abf0dc832740ab {
    padding: 0px;
    margin: 0;
    padding-top: 1em!important;
    padding-bottom: 1em!important;
    width: 100%;
    display: block;
    font-weight: bold;
    background-color: #e6e6e6;
    border: 0!important;
    border-left: 4px solid #000000!important;
    text-decoration: none;
}

the title and link

.sa03dbe163e71ee0412abf0dc832740ab:hover .postTitle {
    text-decoration: underline!important;
}

.sa03dbe163e71ee0412abf0dc832740ab .ctaText {
    font-weight: bold;
    color: #141414;
    text-decoration: none;
    font-size: 16px;
}

The .sa03….class doesn’t help because the divs on other pages also have a different class.

I will appreciate any help in the right direction.

Thank you in advance.
