WordPress custom blocks are easy to develop and unlocks a lot of potentials. This article is our introduction and index article of our Gutenberg Custom Block tutorial series. In this article, we will answer all your questions about what and why you should learn to create custom blocks and you’ll also get the list of articles of our custom block development series.

What is Custom Block?

So first understand what is Custom Block? As the name suggests custom block simply is a block coded by ourselves. Gutenberg introduced a whole new way of creating websites using blocks and with the help of blocks designing and creation a website has become a lot easier (read more about it in this article).

Why should You Learn?

Now let’s understand why you should learn to code custom blocks and what is the benefit of coding our own custom blocks. The first and greatest advantage of coding a custom block is to fully design a site in a way you want no restriction by any plugin or theme and standing out from the competition is the key to success and custom blocks can surely help you in that.

Another great advantage of learning to code custom blocks is to launching your own block plugin. Gutenberg is very new now and very few plugins are available for it and this might be a good chance of creating something your own and launching it.

What’s in This Tutorial?

Well, it’s not an article but complete series of multiple articles designed for absolute beginners so even if you are new in coding you can easily follow along, however, some basic knowledge is still required which we have talked about in detail later in this article.

In this article series, we start from scratch and beginning and we will get to complete advance blocks by the end of the series. We will cover every single required aspect of the custom block so you can build any kind of custom block with full features.

Now if you are thinking about why we are creating multiple articles series, why don’t we create a single article? The answer is because it’s impossible to explain all the things of block in a single article. Custom Blocks are very new and have a lot of parts into them also even documentation for the custom blocks is not fully completed yet so making a series makes more sense for understanding it completely.

What are the Requirements?

Well, we have designed this series for beginners however by beginners we mean beginner for Block Development but you do need some prior knowledge of HTML, CSS, and JS. We will also use two variations of JavaScript ES 5 and ES Next. You may have noticed we haven’t added PHP to the list because that is not an absolute requirement because code will be written in mostly JavaScript.
