I officially declare that "I didn't know HTML & CSS UNTIL TODAY"

My journey into web3 started a bit differently with first learning Solidity and not web development

Today I took the first step of doing a crash course on HTML & CSS

Learnings on Day1👇

#100DaysOfWeb3
📌 HTML

✅ Basic HTML syntax
✅ Headings & Paragraphs
✅ Strong and Emphasis
✅ Anchors and Attributes
✅ Lists
✅ Images
📌 Basic HTML syntax

1. Every HTML page starts with <!DOCTYPE html>- Way to tell the browser that document is written in Version 5 of HTML
2. The four most essential and widely used HTML tags -
<html>
<head>
<title>
<body>

Each and every tag must be closed as well.
📌 Headings & Paragraphs

1. Headings- For showing text as a heading, there are 6 level of tags available starting with <h1>,<h2>,....<h6> wherein size decreases with increase in suffix number
2. Paragraph- <p> tag is used to show some text as paragraph
📌 Strong and Emphasis

How to give make some text bold or italic?

Strong- <strong> tag is used to Bold the text
Emphasis- <em> tag is used to make the text italic
📌 Anchors & Attributes

How to give reference to some other page of our website or some external link on our current webpage?

Anchor,<a> tag help us achieve that. For specifying the link it should redirect to, we use 'href' attribute to specify location like <a href="Link"></a>
📌 Lists

There are two types of List: Ordered and Unordered

Ordered List- Specified with <ol> tag & different way of ordering can be provided by giving different type

Unordered/Bulleted List- Specified with <ul> tag

To specify elements that need to be listed <li> tag is used
📌 Images

How to add an image within the webpage?

<img> tag is used to embed image in a webpage where src specifics the source of image and alt specifies the text explaining what the image is all about like <img src= "abc.jpg" alt= "text">
📌 Basic of Inline CSS

style attribute is used to apply styling to a single HTML element wherein each one of them is stated as a property : value pair inside HTML opening tags

Styling elements I specifically learnt today

✅ font-size
✅ color
✅ background-color
✅ text-align
With this my Day1 learning ends and Here's how my basic web page looks like after learning all of the things mentioned above.

P.S. I know it's not something extraordinary & can be improved but I enjoyed making it😛
For learning all of this, I'm following this amazing course scrimba.com/learn/htmlcss on @scrimba from one of the best tutor @KevinJPowell

What is Ethereum?

Day12 of #100DaysOfWeb3

A Mega Thread👇
The invention of Bitcoin blockchain popularised two major concepts
1. Decentralized currency
2. Blockchain technology

Limitation of Bitcoin: Usage limited to peer-to-peer money transfer over the internet

But can this blockchain technology be leveraged to do more than just that?
📌 Possible solutions to overcome the limitation

- Building a new blockchain with enhanced features: Difficult to implement with high development time
- Building something on top of Bitcoin: Less scalable
- Trying to use programming on top of Bitcoin: Limited capabilities

What is Metaverse? 🤯

Day11 of #100DaysOfWeb3

A Tiny Thread🧵
It's known be the next phase of internet. Just like internet was something revolutionary back in 90s, similar to that metaverse is going to be the next revolutionary thing of the 21st century.
In most simple words, it's a "virtual world" where we'll have digital version of ourselves or avatars and we can can do almost everything which we're able to do in our real lives like learn, shop, play, work, meet friends and what not.

What is Proof-Of-Stake? 🤔

Day03 of #100DaysOfWeb3

👇 A Thread
📌 Why we require Proof-of-Stake consensus mechanism if we have Proof-of-Work?

If you have read my last tweet, you should have at least 1 answer😉

- Negative impact on the environment 🌍
- Expensive to be a miner 💵
- Scalability : Less transactions processed per second⏱
📌 What is Proof-of-Stake?

- It does not have miners but instead validators
- Only who put their crypto on stake become validators
- There is no competition but a validator is picked in a pseudo-random way, who propose to add next block

What is the consensus mechanism : Proof-Of-Work?

Day02 of #100DaysOfWeb3

👇A Thread
📌 What is consensus?
Let's understand it with an example :
If your family is planning to buy a car and if more than half of the persons in the family agree upon a certain model of the car, then we say we have reached a consensus or in simple terms agreement upon something.
📌 What is blockchain consensus mechanism?
Since blockchain is a public distributed ledger and an agreement is required from every node in the network to make any addition to the blockchain, it is nothing but a certain procedure to reach an agreement upon current state of network
