1. CSS isn’t broken β€” your div just gave up on life.
Try: min-height: 100vh; πŸš‘

== is for loose relationships.
Use === if you want commitment. πŸ’

Want faster sites?
Replace PNGs with webp. Smaller, sharper, sexier. πŸ“Έ


2. Centering in CSS used to be sorcery. πŸ§™β€β™‚οΈ
Now it’s just:
display: grid;
place-items: center;


3. Bored of boring bullets?
Spice up your list with:
list-style-type: 'πŸ”₯';


4.
z-index

not working?
Make sure the element isn’t a ghost.
position: relative;

Key trends shaping the future of web development πŸ‘‡πŸ‘‡

1. Progressive Web Apps (PWAs): PWAs are becoming more popular as they combine the best of web and mobile apps, offering a seamless experience across platforms without needing app stores.

2. WebAssembly (Wasm): WebAssembly allows developers to run code written in different languages (C++, Rust) on the web with near-native performance, enhancing web application speed and capabilities.

3. AI-Powered Web Development: Artificial Intelligence (AI) and Machine Learning (ML) will become more integrated into web development, enabling features like chatbots, personalized content, predictive search, and automated design processes.

4. Voice Search Optimization: As voice search continues to grow, web developers will focus on optimizing websites for voice-activated queries, leading to changes in search engine optimization (SEO) practices and user experience design.

5. Serverless Architecture: Serverless computing allows developers to build and deploy applications without managing infrastructure. This reduces costs, enhances scalability, and enables faster development cycles.

6. Motion UI: Animation and micro-interactions will play a bigger role in web design. Motion UI helps create engaging, interactive experiences that can improve user engagement and satisfaction.

7. 5G and Enhanced Connectivity: With the rollout of 5G, faster internet speeds and lower latency will enable more complex, real-time applications, especially in areas like augmented reality (AR), virtual reality (VR), and IoT.

8. Blockchain Integration: Web development could integrate blockchain technology for decentralized applications (dApps), offering enhanced security, transparency, and user control over data.

9. Edge Computing: By bringing computing closer to the source of data, edge computing will reduce latency and improve the performance of web applications, especially for IoT and real-time data processing.

10. Cybersecurity Focus: As web applications handle more sensitive data, the importance of robust security practices, such as multi-factor authentication (MFA), encryption, and secure development frameworks, will grow.

Frontend vs BackendπŸ‘¨β€πŸ’»

Here are the main points about frontend and backend development:

Frontend:
1. Client-side aspect of web development.
2. User interacts directly with the frontend.
3. Includes user interface design, layout, and functionality.
4. Technologies: HTML, CSS, JavaScript.
5. Responsible for what users see and interact with on the browser.
6. Executes on the user's device (browser).

Backend:
1. Server-side aspect of web development.
2. Users don't directly interact with the backend.
3. Manages server, application logic, and database interactions.
4. Technologies: Python, Java, Ruby, etc.
5. Handles user requests, processes data, and sends responses.
6. Executes on the server.
