What does a landing page with a stretch on wordpress mean?

Question

CMS

I always thought that a landing page is a layout + 1 php file for submitting forms.
Why is wordpress needed and what does it look like?
Is the entire layout copied to front-page.php?

Answer 1

Most often, it is enough to do as you said, 1 layout file + 1 file for the form.
But sometimes the client needs to be able to edit everything in a convenient format through the admin panel. Then I make the layout of one page on wordpress, install the plugin for additional fields, and through them I add all the blocks for the landing (this is purely for the sake of convenience for the client). Well, plus it is also convenient to work with forms for the client. As a plus - extensibility. You can make many landing pages, or even expand it into a full-fledged website.
As a result, I get something like this
and the client is happy that everything changes easily

Answer 2

wordpress for the form, replacing images in sliders by the administrator, replacing products (products in the database then), etc. admin area for content, in general. maybe for development (a couple of pages to add in the future).
