Hi Tod,
The code you are using is CSS. So you have to wrap that with <style></style> tag.
Edit the shortcode content to below.
<style>
.intro {
line-height: 30px;
max-width: 70%;
font-family: asul;
color: #910000;
padding: 5px;
margin: auto;
display: table;
text-align: center;
font-size: 20px;
font-weight: 700;
}
</style>
Then you can use [sc name="my-shortcode-name"] in the post.
This will place the above code in the post whenever you use the shortcode.
I’m not sure how the short_intro shortcode come into picture here as that is not related to shortcoder plugin. Please explain in detail if needed. You can also refer this doc about using “enclosed content” here – https://www.aakashweb.com/docs/shortcoder-doc/shortcode-parameters/#shortcode-enclosed-content
Thanks,
Aakash
