Currently working on a Cuba project, bunch of HAML file but for improving UI I still prefer pure HTML, but as I tried, It's seems very complicate to rebuild every thing to get rid of HAML.
Any clues?

From a quick glance at the docs, Cuba can use any template tilt supports. So if you want to switch to ERB (HTML-based template), you'd switch the template engine:
Cuba.settings[:render][:template_engine] = "erb"
And then re-write all of your view code in ERB. Which seems like a lot of work compared to getting used to HAML, but alas.
There are tools to make HAML->ERB conversion easier, like herbalizer.

I have had a great doubt for a long time, and I have been able to observe in some manufacturers that chips and tutorials, such as espressif or microchip technology, use pages with this format in some of their tutorials:
I would like to know if this page format is some standard or is it just a popular template that is often used or generated with some framework?
It would be interesting to be able to implement some identical format, I hope you can help me.
This is made using a document generator, and there are lots of them out there.
The specific one in your image example seem to be Read the docs.
You can look up "documentation generator" or "static documentation generator" for more examples.

I know HTML, CSS & JS. I need to learn react, and I have heard about HTML to JSX extension.
So, is it necessary to learn JSX?
A tool that converts HTML into JSX isn't a substitute for understanding JSX since almost all JSX that you will need in a React application does things beyond outputting something that can be generated from static HTML.
You could, instead, write the JS that would be generated from JSX directly. This would lose you the benefits of the tool you found while also being harder to learn and manage than JSX.

I want to copy and paste mathematical formulas from other websites , the problem is that the formulas change their structure when I paste it to my admin textarea and looks differently in my website.I used CKEditor , but it did not solve my problem.
You can try using MathJax, a JavaScript display engine, to display math on your website. It is simple to get started just by adding this to your page:
<script src='https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js?config=TeX-MML-AM_CHTML'></script>
After that, you can easily start writing mathematical formulas in many notations, i.e. TeX and LaTeX notation, MathML notation, and/or AsciiMath notation.
In fact, StackOverflow uses MathJax as well :)

More specifically what I'm trying to say is, why can't we just use pure HTML for that purpose?
Jade and EJS are templating engines - they allow you to do things like conditional statements and loops, and give you the ability to break the pages into more modular components (for example, you can have one template with the header in it, and then include that in every other page without having to copy and paste the code). That said, there's nothing stopping you using pure HTML - you just won't get any of those features.

Hi I am trying to work out if it is worth using LESSCSS.
After much research and playing I see that it is not supported by older browsers and needs to be compiled before it is used. Is it even worth using? I know that it makes css easier write, but is it even worth it if what you are writing is not what will be on live when it is used?
Thanks
In fact, there are two ways of using LESSCSS :
Client-side : the .less file is sent to client and is executed by the browser, uses javascript and requires recent browser.
Server-side : the .less files are compiled to plain .css files, which are sent to the client.
The second one requires more configuration of the server, but requires nothing more than CSS compatibility from the client.
You can find more details on the LESSCSS main page, at the bottom of "usage" section : here.
