Resize Simple List Body Text

Hi, I used a simple list for a page on a website and the text is a lot smaller than the rest of my website. How can I use css to customize the text size in the simple list? I need to make the text bigger. You can see in the photo the text size in the simple list (upper) doesn't match the text size in the lower section.

Use this CSS

/* List Section Body Text */
.list-item-content__description * {
    font-size: 30px;
}
