Why my customized CSS for a wordpress theme is not working from cpanel?

Question

I am trying to update the CSS of a theme I am using. To test if it works, I am display: none to a div .
Firstly I tried customizing the main style.css file of that theme

.comment-avatar {
    display: table-cell;
    width: 92px;
    margin: 0;
    vertical-align: top;
}

I set it to

.comment-avatar {
    display: none;
    width: 92px;
    margin: 0;
    vertical-align: top;
}

It's not working. But it does work if I edit it from "Addtional CSS" or "Custom CSS" provided in wordpress. But both of these increases the load time of my website.

I am looking around for a way to customize the main CSS file of that theme.

Edit : I am updating the theme's style.css but browser I am seeing that the style is applied from 'style.min.css' file which is also on the root. Aren't my changes to 'style.css' not reflected intp style.min.css automatically?

Answer 1

To your CSS, try to give !important tag as shown below

.comment-avatar {
    display: none !important;
    width: 92px;
    margin: 0;
    vertical-align: top;
}

and then clear the cache.
