Thank you Steve! I wasn’t clear enough. I meant – how do I change just that one product’s font size (and keep the other products’ font sizes the same)…
Hello,
You could target the post ID as well for this specific product.
li.post-17828 h2.woocommerce-loop-product__title {
font-size: 20px !important;
}

What’s the easiest way to access the html file?
There is no need to access the html file to be honest.
You can simply add a Plugin like @sterndata pointed out and make it easier on yourself without accidentally messing something up.
