I've created a newsletter sign up pop up to appear on my home page. I created it a Mailerlite. They provide me with a snippet of code, and gave me these instructions to make it work: "Install the following snippet of Javascript on every page of your website right before the closing </head> tag." Do I use code injection for this? Only on page which will have the pop up? Completely new to coding here.

Site URL: https://www.bodieplecas.com/home I'm a newbie to this. I created an embedded sign up form for a newsletter at Mailerlite. The choices at SS were too limited. I've put it on several pages, and it looks good except for on the homepage, where it needs to be bigger. How can I make it bigger? I think it has to be in the code, not sure. Mailerlite have a javascript code to enter if its necessary, but I don't know if its necessary on SS. Also, is there anything else I need to do so the form links/integrates with Mailerlite? Thank you in advance!

Site URL: https://bodieplecas.com I'm editing my page, and I'd like to reduce the size of the footer. It's a huge black space and I don't need all of it. I just need to be able to put in a subscribe form, links to social, and a picture of my book. SS told me to use padding to reduce the size, but I can't seem to figure it out. I've attached a screenshot of the gigantic footer. I'm 7.0, Brine. Appreciate any help.
