CMS is a ready to use System, You post content from the admin panel and it is shown on the front-end/ public-side of the system.

Wordpress is one of the best CMS availble now a day.

The use of content management system is not only for developers but for clients as well.

• For developers :  its easy to develop and no need to build functionality from scratch. Admin panel is also provided so all that hassle to create user roles and UI is already taken care of.
• For Clients/Admins: It has alot more benefits for clients than developers for e.g one can create dynamic web pages based upon some category of new products, create new articles without doing any programming at all just through UI, modify existing content, create new article pages, manage email campaign and generate autmated newsletters to different group of customer. All these functionalities are provided by CMS and clients do not need to know the programming for doing these exciting tasks.

It will save your time. No need to go for tyring codes and diffulty in extending the functionalities.

Universal coding standards . Plenty of Modules,Plugin,Feature extensions avaialble.Support forums,Code helps etc.

I suggest:

1. Drupal 7 & 8 - difficulty level is intermediate,Exciting Modules ,Views,Rules,Taxonomy,Context,Best support Forum, Secure, limitless extension features, suitable for large,small, highly traffic websites,portals,shopping cart,ecommerce integration etc.
2. Wordpress - Easy to use,A no of plugins,support etc.
3. Joomla- one of the old CMS.It was my first CMS used!

it allow people with zero code experience to build a professional website

the basic reason is the admin panel ,the admin panel designed to make the users understand it from first sight. and it has alot of free themes in deferent categories and also may plugins which add more functionality to the theme without change the code.
