What we're building
Stage 1
(HTML Only)
Stage 2
(HTML + CSS)
Stage 3
JS
Create a portfolio returns calculator
Before we start
What are browsers? How do they render websites?
What purpose do HTML/CSS/JS serve
How much of this do we actually use in the industry -
1. html => very minimal
2. css => minimal
3. js - heavy
IDE
VSCode
Vim
WebStorm
HTML
Defines the structure of your website
2 jargon we need to know of -
1. Tags
2. Attributes
HTML Tags
- <html>
- <head>
- <title>
- <body>
- <div> / <span>
- <h1> .. <h6>
- <p>

How to add styles?
How to add styles?
Common styling attributes
color
background
border-radius
border
padding / margin

divs always take up all the space available horizontally
spans only take up as much space as needed
Can you make divs take only the space they need?
Title Text
How to position?
Dumb way
float property
Flex box
Right way
display: flex
on parent
makes all div siblings reside
in the same line
Flex box
Javascript
It is a scripting language
It can be used to solve algorithmic problems/do ML/do backend development
Specifically for websites, it is useful to add functionality to your website (for example, a returns calculator)
We're going to practise on repl.it first
For JS (or any language), you need to know
- variables
- Simple Data types (strings, numbers, boolean)
- Complex Data types (arrays and objects)
- Control statements and operators
- Loops
- Functions
Problems to understand these
1. Count from 1 to 1000
2. Is Palindrome?
3. Find the name of the oldest person in a group
Take home assignment -
