Why HTML as the language of web pages in Intro to Computing? - Purpose & Use Cases
The Scenario
Imagine you want to create a simple webpage by writing everything manually in a text file without any structure or rules. You try to add headings, paragraphs, images, and links just by typing words and symbols randomly.
It feels like writing a letter without paragraphs or punctuation, making it hard to read or understand.
The Problem
Without a standard way to organize content, browsers don't know how to display your page properly.
Each browser might show your text differently, or not show images and links at all.
It's slow and frustrating to fix because there's no clear method to tell the browser what each part means.
The Solution
HTML provides a simple, universal language with clear tags to structure your webpage.
It tells browsers exactly what is a heading, paragraph, image, or link, so they can display your page correctly and consistently.
This makes building and sharing webpages easy and reliable.
