Standard forms
Our ideal form markup
Newsletter Sign Up - Octopus Forms Plugin
Octopus is something like Mailchimp - a newsletter service.
This form can be found on the website here: https://beta.dorothyhouse.org.uk/subscribe/
I've replicated it here, and activated both success and error messages with the class `emailoctopus-fadein`
It has it's own base styles which you can find at: `/assets/css/octopus-forms-plugin.css`
Whilst there are themes in the WP Admin, they don't actually do much to the appearance.
Contact Forms - Contact Forms 7 Plugin
This plugin form can have the markup completely altered to suit us.
It has it's own base styles which you can find at: `/assets/css/cf7-forms-plugin.css`, however, it also has the ability to switch these off.
