Background image on Text section

[virtualinternships]

I am trying to input a section with a newsletter (via a plugin) with a background image. To use a plugin, I have created a text section and entered the plugin shortcode.
First, is the only way to edit the functionality of the plugin via the shortcode? (i.e. I need to review the documentation of the plugin)
Secondly, how do I input a background image for the text section? I have tried putting a class in the custom css:
$e1 {
background-image: url(‘https://virtualinternshipscom.blog/wp-content/uploads/2018/05/newsletter-cropped-green-overlay.png’);
}
This was following the instructions.
However, the image does not appear. How do I make the image appear?

Thanks

Hi There,

That custom CSS should be put the Element CSS instead of the Class:

Hope it helps

Hi there

Yes, I have now made it work. Thank you for your help.

Any word on the question regarding the plugin shortcode?

Thanks

Hi There,

You can insert the plugin short code via classic raw content instead of text element.

Thanks
