The "viewport" meta tag is used to configure the visible area of a web page on mobile devices, ensuring proper display and responsiveness on various screens.

Caching in web development involves storing and reusing previously loaded web page resources (e.g., images, scripts). It is beneficial for speeding up page loading times and reducing server load.

Validation in web development involves checking web content for compliance with web standards, ensuring error-free and standards-compliant code. It's important for consistency and cross-browser compatibility.

The "robots.txt" file in web development is used to instruct web robots (search engine crawlers) about which parts of the site they should or should not access.

The Single Responsibility Principle (SRP) in web development suggests that each class or function should have a single reason to change, promoting maintainability and separation of concerns.

User-centered design in web development is a design approach that prioritizes the user's perspective and needs, ensuring a positive user experience and usability.

A/B testing in web development involves comparing two versions of a web page to determine which one performs better with users. It is used to optimize user experience and achieve specific goals.

HTTP/2 is the latest version of the HTTP protocol that offers faster and more efficient data transfer, reducing page load times and improving performance.

Content strategy in web development is a strategy for creating and managing digital content to meet user needs and business goals. It is important for providing valuable and relevant content to users.

Responsive images in web development are images that automatically adjust their dimensions based on the screen size, ensuring proper display on various devices and screen resolutions.

The "Viewport Meta Tag" is used to configure the visible area of a web page on mobile devices, ensuring proper display and responsiveness.

HTTP/3 is the latest version of the HTTP protocol, offering improved speed and security compared to previous versions.

Cross-Origin Resource Sharing (CORS) is a mechanism that allows or restricts web pages to request data from other domains. It is important for security and data access.

Semantic versioning (SemVer) is a versioning system that indicates changes in software or libraries using a structured format. It is used to communicate the impact of updates and changes.

In CSS, "cascading" refers to the process of determining which styles apply to an element when multiple rules conflict. It is important for understanding how styles are applied.

Graceful degradation in web development ensures that web pages work on a basic level for all users, even if some features are not supported, providing a consistent user experience.

Cross-Site Scripting (XSS) is a security vulnerability in web development where malicious scripts are injected into web pages. It is a significant concern for protecting user data and privacy.

Website performance optimization in web development is the process of improving the speed and efficiency of a website. It is important for providing a better user experience and reducing bounce rates.

HTTPS is a protocol for secure communication over the internet, ensuring that data exchanged between a user and a website is encrypted and secure. It is important for protecting user data.

"WAI-ARIA" stands for "Web Accessibility Initiative - Accessible Rich Internet Applications." It is a set of attributes for enhancing the accessibility of web content, especially dynamic content and advanced user interface controls.

Google PageSpeed Insights is a tool used to analyze and optimize web page performance. It provides recommendations for improving loading times and user experience.

Responsive typography in web development involves designing text elements that adapt to different screen sizes and devices, ensuring readability and aesthetics. It is used to enhance user experience.

"Alt text" is text that describes the content of images, and it is important for both accessibility (making images understandable to people with disabilities) and SEO (search engine optimization).

Asynchronous loading of JavaScript in web development allows JavaScript to load without blocking other web page elements, improving page performance and user experience.

Content Security Policy (CSP) is a security feature in web development that helps prevent cross-site scripting (XSS) attacks by controlling which resources can be loaded by a web page. It is important for website security.
