A complete beginner's guide to CSS Grid layout 👇🏻

Thread🧵

Grid is used for making complex web design layouts more easily as it's not so hard to master

Using Flex you can make only 1D layout but Grid gives you full power of creating 2D layout

Let's start

{ 2 / 21 }

First things first, start with giving the display property "grid" to the container element or parent element

{ 3 / 21 }

Nothing will change after adding display: flex; in the parent container becuase we need to define the width of columns. In order to set that columns width we have gird-template-columns property

{ 4 / 21 }

Let's start with defining the width of our columns.

For example, let's say I need two columns of width 60% and 40% respectively

grid-template-columns: 60% 40%;

{ 5 / 21 }

React Hooks are so powerful and especially some additional hooks.

Do you know there is an alternative to useState called useReducer hook? It is used to manage more complex states.

Let's look into detail 🧵👇🏻

Usually, the useState hook is used to tackle states in React where you can pass the initial state and React preserves state for you between re-renders

What if you need to manage more complex states? Here useReducers comes into play

Similar to useState, the useReducer hook also returns a pair of values. Let's see what these two things are

The first value is `undefined` which is the current state (it is undefined because we didn't pass any initial state in the useReducer hook)

The second value is a dispatch function using which we can update our state.

The useReducer hook accepts 3 parameter

1. reducer
2. Initial state
3. init

React Hooks are the functions which "hook into" React state and lifecycle features from function components. Hooks allows you to manipulate state and other React feature without writing a class. Let's talk about widely used hook

useEffect hook at a glance 🧵👇🏻

useEffect hook is the heart of React functional components

If you're familiar with class components then you might know that we have various lifecycle methods but in functional components, we don't have any lifecycle methods. Instead we have a powerful hook called useEffect

By using useEffect, you tell React that your component needs to do something after render. React will remember the function you passed (we'll refer to it as our “effect”), and call it later after performing the DOM updates

So let's start by understanding the syntax first

3/15

useEffect take two parameters, first is a function and second is an array.

The function inside the useEffect will run every single time component re-render. Consider this piece of code and check the output in next tweet

{ 4 / 15 }

As you can see in the output the function is executed every single time my component re-render

{ 5 / 15 }
