Which Software is Used to Read and Render a Program in HTML?
FREE
An HTML web page needs to be both read and rendered. A web browser is used to support HTML web pages, read them, and render them. The programmer creates an html web page by saving the document with the .html extension, and any web browser that accepts the .html file format can open the file as a web page.
Web browsers like Google Chrome, Safari, and Microsoft Edge can be used.

How Browser Rendering Works ?
An HTML web page can be read and rendered by using a web browser. A web browser is an essential component facilitating user interaction. Every major browser's engine is a basic software component, and different browser manufacturers refer to their engines by different names. For example, Google Chrome's engine is called Blink.
The browser hierarchically processes the HTML data.
-
First, the raw data present on the HTML page is processed. This would result in the user specifying a user destination. Then, the server would initiate a response.
-
Next, the raw data is broken into component characters which are processed.
-
Following this, characters are chunked into individual tokens, which are then processed.
-
These tokens are parsed over by the web browsers and rendered accordingly.
-
After the tokenization is done, the tokens are then converted into nodes. Each node is an individual component on a tree of webpage elements.
-
The nodes are then linked in data structures known as the DOM (Document Object Model) and the CSSOM (CSS Object Model) . The DOM is responsible for establishing the various relationships between HTML components.CSSOM is similar to DOM, but instead of specifying document properties, it specifies layout or CSS properties.
-
The Render tree is an amalgamation of the DOM tree and the CSSOM tree.
The DOM tree is used to specify the structural components on the webpage.
The CSSOM tree is used to specify the layout characteristics of the HTML components described in the DOM tree.
The render tree is an amalgamation of both the DOM tree and the CSSOM tree which shows the visible components.

Conclusion
- A web browser is used to render HTML documents.
- Every browser has an engine for visually representing the HTML document.
- The steps for processing are :
raw data characters tokens. - Tokens are further converted into nodes, which are systematically arranged to form a DOM.
- The DOM is responsible for establishing the various relationships between HTML components while CSSOM is responsible for establishing the various relationships between CSS components.
