How to direct CSS at a single page

I’ve been working and able to solve a lot of my problems using the custom CSS thanks to all of the support I found on here, however it applies to all pages or widgets or whatever. What I want to be able to do is target each page individually. How would I do that?

Example of the CSS Im using that I want to target at a page:
.page-title {display:;
text-align: center;
font-style: bold;
font-size: 70px;

.page-title-section {display:;}
.content-area {padding-left: 10cm;}



You can limit that using Page ID like,

.page-id-1133 .page-title { display: none; }

You can find the page id like this,
