How to remove page and post titles on Weaver

Hello,

This is the site I am building https://www.rubyharte.com/ and I am attempting to hide the page and post titles – I am using the Weaver Theme.

In the Snippets Section this is written:

Hide Page and/or Post Titles
If you don’t want your page titles to show, you can use the following snippet:

.page .entry-title{display:none;}
You can do the same for posts with:

.post .entry-title{display:none;}

I have followed the instructions (I think)

<!– Add your own CSS snippets between the style tags. –>
<style type=”text/css”>
#access {-moz-border-radius: 7px; border-radius: 7px;
-webkit-border-radius: 7px;}
#access { text-align:center; }
#access ul{display:inline-block;}
#page .entry-title{display:none;}
#post .entry-title{display:none;}
#comments {display:none;}

</style>

The other code snippets I have added are working. Do you know what I am doing wrong? Or know how I can accomplish what I want?

I have not yet learned CSS.

Thank you
