Hi Julia,
It’s possible, but it would be difficult.
Instead, I would use the body class.
Each page is given a unique class with the page ID – you can see it by using your Inspect Element tool in your browser.
The <body>
element should have a class like this: page-id-xx
“xx” being the ID of the page.
So you can target individual entry-title elements like this:
.page-id-xx .entry-title {
/* CSS to make this one entry title different */
}
Let me know if you need more info 🙂
