Is it possible and reasonable to convert a complicated, heavily styled html page into an editable Drupal site page? I already read this:

How to convert an HTML website to Drupal 7 nodes?

and this:

https://www.drupal.org/node/313510

and some more.

Hello,

I have been tasked with creating an editable version of an html page that is heavily based on this template's design:

(not trying to advertise, just to give an idea)

I have read and learned about Drupal in the past week and have reached the point where I feel comfortable:


Tweaking themes.
Adding articles, polls and such plain content.
Messing around with the admin panel.


I don't understand how one would add content that is less "straight forward" to a Drupal site. Is it reasonable to do? Can it be done more easily with other CMSs (like Wordpress)? Should I tell my boss that the CMS should be used for news and articles in other areas of the site but NOT this specific promotional page?

From what I read I realize that I could create a rather complex view and a gazillion nodes and use that to generate an editable promotional page that looks like this template. My concern is that it may turn out unfriendly to the content professional.

I really would like to hear some expertly advice on how reasonably doable the task of creating an editable version of the promotional html page is in Drupal (that looks like the original).
You can use drupal to develop and complexity of site including that of a complex css design.  I personally work for a digital agency and every single project I have been on has been built in drupal and has been heavily design oriented.  I have also built JS apps in drupal as well.

If you are looking for a theme out of the box then you probably wont find it as they are generally free and not a whole lot of design into them.  If you are comfortable or willing to learn to create your own theme and template files then you most certainly can do this inside drupal.

It all depends on your level of knowledge and effort.

Here are a few heavy sites designed in drupal:

With drupal you have CSS, PHP, and MYSQL which means you can do anything those technologies can.

EDIT***

Also to answer your question more specific it really depends on how much of the content will be editable.  Drupal provides a more flexible GUI type layout called panels and panelyzer that provides more of what you may need.  Research into Panopoly distribution as its geared more towards landing pages
