Themes Development – How to Design & Subscribe to Blog & # 39; via CSS

I want to design a feature & subscribe to a blog & # 39; on my WordPress blog using CSS.

I'd incorporate this subscription feature into my sidebar as well as into the footer. However, I am not technically sound when it comes to WordPress file modifications.

P.S. – I am currently using the Baskerville theme & # 39; on my WP blog

Previously, I used the Jetpack plugin. But lately, the plugin has terribly messed up the layout of my blog and has affected many other features. I was therefore forced to permanently delete it from my list of plugins.

I am not in favor of using optional forms for this and would prefer to design it myself. So, if there is a CSS code that can help me design a custom "Subscribe to a blog" feature, please share it.

Thank you.
