Study Notes
Introduction
Web development is the process of creating websites and web-based applications. It involves a wide range of technologies and concepts, including HTML, CSS, JavaScript, and backend development. In this article, we will explore these subtopics in detail, and provide an overview of the web development process.
HTML
HTML (Hypertext Markup Language) is the standard markup language used to create web pages. It is used to structure and format the content on a web page, including text, images, and other multimedia. HTML is a markup language, meaning it uses tags and attributes to define the structure and content of a web page.
Some key features of HTML include:
-
Semantic tags: HTML5 introduced a number of new semantic tags, such as
, - Accessibility: HTML includes a number of features that help make web pages more accessible to users with disabilities, such as the ability to add alternative text to images and the ability to specify the language of a web page.
- Responsive design: HTML provides a number of features that can be used to create responsive web designs, such as the ability to use media queries to apply different styles based on the size of the user's device.
Responsive Web Design
Responsive web design is the practice of creating web pages that are able to adapt to the size and shape of the user's device. This is important because users access the web on a wide range of devices, including desktop computers, laptops, tablets, and smartphones, and it is important that web pages are able to display correctly on all of these devices.
Some key concepts in responsive web design include:
- Media queries: Media queries allow developers to apply different styles based on the size of the user's device. For example, a developer might use a media query to apply a different layout to a web page when it is viewed on a small screen.
- Flexible grids: Flexible grids allow developers to create layouts that can adapt to the size of the user's device. For example, a developer might use a flexible grid to create a three-column layout that becomes a single-column layout when viewed on a small screen.
- Fluid images: Fluid images are images that are able to resize themselves to fit the space available on the user's device. This allows images to display correctly on devices with different screen sizes.
Backend Development
Backend development refers to the server-side of web development, which involves working with the technologies and concepts that run on the server and handle the logic and data storage for a web application. Some key technologies and concepts in backend development include:
- Databases: Databases are used to store and retrieve data for web applications. There are many different types of databases, including relational databases (such as MySQL and PostgreSQL) and NoSQL databases (such as MongoDB and Cassandra).
- APIs: APIs (Application Programming Interfaces) allow different software applications to communicate with each other. They are commonly used to allow web applications to access data from other sources, such as a database or a third-party service.
- Servers: Servers are used to host web applications and serve them to users over the internet. There are many different types of servers, including web servers (such as Apache and Nginx) and application servers (such as Tomcat and JBoss).
CSS
CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation of a document written in HTML. It is used to specify the layout, colors, and other visual aspects of a web page. CSS is an important part of web development because it allows developers to separate the presentation of a web page from its structure and content, which is defined in the HTML.
Some key features of CSS include:
- Cascading: CSS uses a cascading system to determine which styles are applied to an element. This means that styles defined later in the stylesheet take precedence over styles defined earlier, unless they are explicitly overridden.
- Selectors: CSS uses selectors to target specific elements on a web page. Selectors can be based on the element's tag name, its class or id attribute, or its position in the document.
- Properties: CSS uses properties to define the visual aspects of an element
