It is easy and simple to build a website with Jekyll. An advantage of using Jekyll is the ability to support MathJax, which means I can write LaTeX-like equations that get nicely displayed in a web browser, like this one \( \mathsf{ 3^2 + 4^2 = 5^2} \).
What’s MathJax? If you check MathJax website you’ll see that it is an open source JavaScript display engine for mathematics that works in all browsers.
