distill: changing font size of description section (text under title)

[zoowalk]

I am trying to change the font of distill's short description text under a blog post's title/heading. I am able to identify the pertaining css selector with the inspector tool in the chrome browser.

d-title p {
    font-weight: 300;
    color: green !important;
    font-size: 1.2rem;
    line-height: 1.55em;
    grid-column: text;
}

Unfortunately, when adding this code to my css file of my blog I don't see any changes. (But I am able to incorporate changes with other properties). Any idea what I could be doing wrong? Many thanks.

Ok, there was an issue with refreshing the cache of the browser. The css chunk above is correct.
