Can’t force style

I added the following code into my theme files to get post excerpt to display at top of each post:

<div class=”post-page-excerpt”>
<?php the_excerpt(); ?>
</div>

As you can see in the link, the excerpt is displaying where I want it to just below the title. I cannot however change the style of this text. I have tried using Google Fonts plugin using the CSS selectors .post-page-excerpt and div.post-page-exerpt. I have also checked the “Force Styles Override” box. No luck. When I go into the Customizer, I can style some things like text background color and character spacing. But I cannot change font style, size or weight.

I also tried changing font size in my style sheet using the same CSS selectors and !important. It did not work.

Any help? The theme is Dazzling.
