HTML comments are not displayed in the browser, but they can help document your HTML source code.
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 0969470341

Swap text for background images with the image replacement class.
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.
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
Display property Quickly and responsively toggle the display value of components and more with our display utilities. Includes support for some of the more common values, as well as some extras for controlling display when printing.
List group List groups are a flexible and powerful component for displaying a series of content. Modify and extend them to support just about any content within.
One of the many great parts of React is how it makes you think about apps as you build them. In this document, we’ll walk you through the thought process of building a searchable product data table using React.
It lets you compose complex UIs from small and isolated pieces of code called “components”. React has a few different kinds of components, but we’ll start with React.Component subclasses:
