  • How to use CSS media queries to make web pages responsive and adaptive to different screen sizes and devices?



The key takeaways and tips from this chapter are:



  • HTML is a markup language that uses tags to define the structure and content of a web page. A tag consists of a name and optional attributes enclosed in angle brackets. A tag can have a corresponding closing tag or be self-closing. A web page is composed of a head section and a body section. The head section contains information about the web page such as title, meta data, links to style sheets, etc. The body section contains the visible content of the web page such as text, images, links, etc.



  • CSS is a style sheet language that uses rules to specify how HTML elements should look and behave on a web page. A rule consists of a selector and a declaration block. A selector identifies which HTML elements the rule applies to. A declaration block contains one or more declarations that define the style and format of the selected elements. A declaration consists of a property and a value separated by a colon.



  • There are four ways to apply CSS styles to a web page: inline styles, internal styles, external styles, and style classes. Inline styles are written inside the HTML element using the style attribute. Internal styles are written inside the head section of the HTML document using the style element. External styles are written in a separate file with the .css extension and linked to the HTML document using the link element. Style classes are reusable sets of CSS declarations that can be applied to multiple HTML elements using the class attribute.



  • CSS properties can be used to style and format various aspects of web page elements such as font family, font size, font weight, font style, text alignment, text decoration, text transformation, color, background color, background image, background position, background repeat, border width, border style, border color, border radius, margin top, margin right, margin bottom, margin left, padding top, padding right, padding bottom, padding left, display type (block or inline), position type (static or relative or absolute or fixed), top offset, right offset, bottom offset, left offset, width, height, etc.



  • CSS media queries are conditional statements that apply different CSS rules based on certain criteria such as screen size or device type. They can be used to make web pages responsive and adaptive to different screen sizes and devices by changing the layout or appearance of web page elements accordingly.



Chapter 3: JavaScript and jQuery




This chapter covers the basics of web programming using JavaScript and jQuery. JavaScript is a scripting language that can add interactivity, functionality, animation, validation, etc. to web pages. jQuery is a JavaScript library that simplifies common tasks such as selecting elements, manipulating elements, handling events, making AJAX requests, etc. The topics covered in this chapter are:

The key takeaways and tips from this chapter are:



  • JavaScript is a scripting language that can run on the client-side (browser) or the server-side (Node.js). It can manipulate the HTML and CSS elements of a web page dynamically and respond to user actions and events. It can also communicate with the web server and other web services using AJAX (Asynchronous JavaScript and XML).



  • jQuery is a JavaScript library that simplifies common JavaScript tasks and makes the code more concise and readable. It can select HTML elements using CSS-like selectors and apply various methods to them such as changing their attributes, styles, content, etc. It can also create and manipulate HTML elements on the fly. It can also add effects and animations to HTML elements such as fading, sliding, hiding, showing, etc. It can also make AJAX requests to the web server or other web services using simple methods such as get, post, load, ajax, etc.



  • To use jQuery, you need to include the jQuery library file in your web page using the script element or link to it from a CDN (Content Delivery Network). You also need to wrap your jQuery code inside a document ready function that ensures that the HTML document is fully loaded before executing the jQuery code.



Chapter 4: XML and JSON




This chapter covers the basics of data representation and exchange on the web using XML and JSON. XML stands for eXtensible Markup Language. It is a language for creating structured and self-describing data. JSON stands for JavaScript Object Notation. It is a format for representing and exchanging data using key-value pairs.

  • XML is a markup language that uses tags to define the structure and meaning of data. A tag consists of a name and optional attributes enclosed in angle brackets. A tag can have a corresponding closing tag or be self-closing. An XML document is composed of a root element that contains one or more child elements. An XML document can also have a prolog that contains information such as version, encoding, DTD, etc.



  • JSON is a format that uses key-value pairs to represent data. A key is a string enclosed in double quotes followed by a colon. A value can be a string, number, boolean, null, object, or array. An object is a collection of key-value pairs enclosed in curly braces. An array is a collection of values enclosed in square brackets.



  • XML and JSON are both used for representing and exchanging data on the web, but they have some differences. XML is more verbose and complex than JSON, but it is more flexible and extensible. JSON is more concise and simple than XML, but it is less expressive and standardized. XML is more suitable for complex and hierarchical data, while JSON is more suitable for simple and flat data.
