What is a Web Worker?

What is CSS?
CSS stands for Cascading Style Sheets
CSS describes how HTML elements are to be displayed on screen, paper, or in other media
CSS saves a lot of work. It can control the layout of multiple web pages all at once

CSS selectors are used to "find" (or select) the HTML elements you want to style.
We can divide CSS selectors into five categories:
Simple selectors (select elements based on name, id, class)
Combinator selectors (select elements based on a specific relationship between them)
Pseudo-class selectors (select elements based on a certain state)
Pseudo-elements selectors (select and style a part of an element)
Attribute selectors (select elements based on an attribute or attribute value)
We have created some responsive starter templates with CSS.
You are free to modify, save, share, and use them in all your projects.
Easily extend form controls by adding text, buttons, or button groups on either side of textual inputs, custom selects, and custom file inputs. 0680448354

Passing Data Through Props To get our feet wet, let’s try passing some data from our Board component to our Square component.
We strongly recommend typing code by hand as you’re working through the tutorial and not using copy paste. This will help you develop muscle memory and a stronger understanding.
What is HTML Web Storage? With web storage, web applications can store data locally within the user browser.
Before HTML5, application data had to be stored in cookies, included in every server request. Web storage is more secure, and large amounts of data can be stored locally, without affecting website performance.
Unlike cookies, the storage limit is far larger (at least 5MB) and information is never transferred to the server.
Web storage is per origin (per domain and protocol). All pages, from one origin, can store and access the same data.
