Changing the Blog Excerpt Text Size in Foster

I'm using the Foster template, does anyone know how I can change the blog excerpt text size?

@PBLMagazine Foster Demo has no excerpt, so can you share your site url to check?

past this code in custom css box

.sqs-block-html .sqs-block-content>*:last-child {
   margin-bottom: 0;
   font-size: 18px;
}

This changed Heading 3 font size not the excerpt, not sure how to edit it to change excerpt for blogs instead

Yup! So you can visit it here with the password "testing"https://smilodon-dory-yllm.squarespace.com/

So this would be for the excerpt under the big blog that says "baring it all on the true brazilian"

@PBLMagazine Please share access password

It's "testing" :)

@PBLMagazine Add to Home > Design > Custom CSS

div#block-yui_3_17_2_1_1566829344134_186696 .summary-excerpt p {
   font-size: 50px !important;
}

You are amazing! Would I be pushing it if I asked if you knew how to make the space between that excerpt and the blogs underneath it a little smaller as well ?

@PBLMagazine Some CSS can solve. I'll send later. Storming here. :(

@PBLMagazine The second post in Latest News, the headlines are in 2 lines, and the font size is a bit too big, so it creates a space in the first post.The code below may improve somewhat, but I think it's better to reduce the font size of the title (second post and other).

/* 5 posts padding top */
div#block-yui_3_17_2_1_1566766146767_50839 {
   padding-top: 0;
}
/* Baring it padding bottom */
div#block-yui_3_17_2_1_1566829344134_186696 {
   padding-bottom: 0;
}

Dude this has been super helpful, thank you so much! and I hope the storm has passed :)
