How can I change the appearance of blockquotes?

I'm trying to change the appearance of my blockquotes. I'm using this CSS:

blockquote {
   width: 90%;
   border-color: #ef420d;
   border-width: 5px 5px 5px 5px;
   border-style: solid solid solid solid;
   padding: 5px 5px 5px 5px;
   background-color: #eee;
}

But only the width: 90% line is having any effect. The rest of the blockquote appearance is unchanged. What am I doing wrong?

Here is my CSS for my personal site. Hopefully, you can manage to swap in what you want.

.quote-block .quote {
background-color: #f5f5f5;
padding: 30px 20px 30px 55px;
font-family: Georgia, serif;
font-size: 14px;
letter-spacing: 1px;
font-style: italic; 

blockquote {
   margin: 0 30px;
}

span {
   display: block;
   font-size: 64px;
   margin-left: -55px;
   margin-bottom: -45px;
   padding-top: 20px;

   &:last-child { display: none; }

}

}

.quote-block .source {
   background-color: #eee;
   color: #4cb982;
   padding: 5px 20px;
   font-style: italic;
}

I've had some blockquote issues using different templates. Some seem to need the !important tag. Try adding it after each line like this and see if it does the trick.

blockquote {
   width: 90% !important;
   border-color: #ef420d !important;
   border-width: 5px 5px 5px 5px !important;
   border-style: solid solid solid solid !important;
   padding: 5px 5px 5px 5px !important;
   background-color: #eee !important;
}

This did the trick, thanks!

Can someone here tell me what CSS to use to just change the font color of the quote block? I am using the Marquee Template and it wont let me adjust the color in the style editor. I'd really appreciate it, thanks

is this code all you have to insert to the header? In my case (montauk template) it does not do anything and the "span" and "blockquote" lines are even considered errors (shown in red)...

doesn't something like this

blockquote {color: yellow; }

or

blockquote {color: yellow !important; }

work?

So very helpful - thanks!
