Creating a website requires the knowledge of HTML (Hypertext markup language), CSS(cascading style sheet) and javascript, but with content management systems like Joomla, WordPress, blogger e.t.c, you can create websites even if you don't know how to write codes.
Using a content management system, usually abbreviated as "CMS" has its pros and cons. Some of the advantages include; no programming knowledge required to create websites, create websites faster, good for creating blogs, news websites and company's information website. One major disadvantage is that websites built with content management system cannot be customised to add features that are not in the framework of the CMS.
If you want to build an HTML website from scratch without a content management system. Take a look at this post Create your first HTML website from scratch.
In this article, you’ll learn how to first develop websites on your local system before deploying the website to a production server with a registered domain(if you don't know how to register a domain, click here). Developing a website in a local environment has its benefits.
First, if you don't have the money to purchase a hosting account yet, you can design and test the website on your system. Second, you won't always need an Internet connection to design your website as a result of which your development will speed up as you won’t have to wait for files to upload when you make changes.
We will be creating a demo website for a dummy company named briltech. Briltech is an information technology company that designs web applications and software for its clients.
