As a developer, you cannot deny the relevance of HTML and CSS in the realm of web development. These two technologies are the foundation of every website, offering structure, style, and functionality to provide a smooth user experience. CSS is responsible for a webpage's design and layout, whereas HTML supplies the structure. Understanding the different functions of these technologies and their respective strengths is critical for any web developer.
In this post, we'll look at the distinctions between HTML and CSS, their distinctive characteristics, and how they work together to bring web pages to life. In addition, I'll discuss how these technologies work with ReactJS, a popular JavaScript library utilized in the HNG internship program.

HTML: The backbone of web structure.
HyperText Markup Language (HTML) is the standard language for developing web pages. It acts as the foundation of a website, defining its structure and content. Here are some important points concerning HTML.

1. HTML uses elements and tags to define webpage content, including headings, paragraphs, images, and links. For example:

   Heading

   : defines a heading

   This is a paragraph

   : defines a paragraph of text : defines an image
2. Document Structure: HTML offers semantic structure for web documents. Elements such as , , , and enhance content organization and accessibility.
3. HTML elements can include attributes to provide more information. For example, the src attribute in a element indicates the image source, but the href attribute in a tag identifies the link destination.
4. Forms and Input: HTML creates forms for user input. Creating interactive forms requires elements such as , , and . CSS: The Art of Styling CSS describes a web page's layout, colors, fonts, and design.

Here are some important features of CSS:

1. CSS Selectors and Properties: CSS targets HTML components and styles them. Each style rule consists of a selector and a declaration block with attributes and values. Here is an example for you: h1 {  color: blue;  font-size: 24px; } 2.Box Model: CSS utilizes the box model to arrange items on a page. The box model has margins, borders, padding, and the actual content area. Understanding the box model is required for accurate element location. 3.Flexbox and Grid: CSS has advanced layout modules such as Flexbox and Grid, which give powerful tools for creating complex and responsive layouts. Flexbox is best for one-dimensional layouts, while Grid works well for two-dimensional layouts. 4.Responsive Design: CSS supports responsive web design using media queries. Media queries let developers to utilize different styles depending on the device's screen size, ensuring a consistent user experience across multiple devices.
2. CSS enables dynamic effects on web pages through animations and transitions. HTML elements are seamlessly animated using properties such as transition, animation, and keyframes.

Key Differences Between HTML and CSS:

1. HTML defines a webpage's structure and content, while CSS styles and layouts the page.
2. HTML employs tag-based grammar, while CSS applies styling to HTML elements using selectors.
3. HTML prioritizes content and semantic meaning, while CSS focuses on visual display and design.
4. HTML and CSS compliment each other. CSS enriches HTML by adding style and layout, making online pages visually appealing and user-friendly. I recently started an internship at HNG, and I would describe it as a very interesting experience. Though I am still learning from Udemy, I am confident that with time, I will improve and I can't wait to begin learning with great minds there. You can benefit from this as well by applying here https://hng.tech/internship and you can also apply for https://hng.tech/premium which provides you with a certificate, Daily job offers, online events for techies, remote job offers, tech talks, coding gigs, annual meetups, networking opportunities, and engaging discussions. Don't miss out on this opportunity my friends.

CONCLUSION
To summarize, HTML and CSS are two critical technologies that work together to build a strong web application. HTML serves as the foundation for structure and content, while CSS adds style and visual flare. ReactJS takes it to the next level by allowing for reusable components and efficient state management.
As we start to work on our HNG project using ReactJS, I'm looking forward to seeing how these technologies will work together to provide a smooth user experience. With HTML's stable foundation, CSS's styling capabilities, and React's component-based approach, we'll be able to create a powerful online application that is both visually appealing and functionally sound.
I appreciate you reading.
