Design for Mobile First
Always Design for Mobile First
Mobile First means designing for mobile before designing for desktop or any other device (This will make the page display faster on smaller devices).
This means that we must make some changes in our CSS.
Instead of changing styles when the width gets smaller than 768px, we should change the design when the width gets larger than 768px. This will make our design Mobile First:

What Are We Building?
In this tutorial, we’ll show how to build an interactive tic-tac-toe game with React.
You can see what we’ll be building here: Final Result. If the code doesn’t make sense to you, or if you are unfamiliar with the code’s syntax, don’t worry! The goal of this tutorial is to help you understand React and its syntax.
We recommend that you check out the tic-tac-toe game before continuing with the tutorial. One of the features that you’ll notice is that there is a numbered list to the right of the game’s board. This list gives you a history of all of the moves that have occurred in the game, and it is updated as the game progresses.
You can close the tic-tac-toe game once you’re familiar with it. We’ll be starting from a simpler template in this tutorial. Our next step is to set you up so that you can start building the game. 0920198622
Handling events with React elements is very similar to handling events on DOM elements. There are some syntax differences:
React events are named using camelCase, rather than lowercase.
With JSX you pass a function as the event handler, rather than a string.
HTML Versus XHTML XHTML is a stricter, more XML-based version of HTML.
What is XHTML?
XHTML stands for EXtensible HyperText Markup Language
XHTML is a stricter, more XML-based version of HTML
XHTML is HTML defined as an XML application
XHTML is supported by all major browsers
XML is a markup language where all documents must be marked up correctly (be "well-formed").
XHTML was developed to make HTML more extensible and flexible to work with other data formats (such as XML). In addition, browsers ignore errors in HTML pages, and try to display the website even if it has some errors in the markup. So XHTML comes with a much stricter error handling

Form Elements This chapter describes all the different HTML form elements.
The input Element
One of the most used form element is the input element.
The input element can be displayed in several ways, depending on the type attribute.
Buttons Use Bootstrap’s custom button styles for actions in forms, dialogs, and more with support for multiple sizes, states, and more.
Responsive Images Responsive images are images that scale nicely to fit any browser size.
Using the width Property
If the CSS width property is set to 100%, the image will be responsive and scale up and down:
Notice that in the example above, the image can be scaled up to be larger than its original size. A better solution, in many cases, will be to use the max-width property instead.
Using the max-width Property If the max-width property is set to 100%, the image will scale down if it has to, but never scale up to be larger than its original size
