Understanding HTML and CSS

What is HTML and CSS?

HTML (HyperText Markup Language) and CSS (Cascading Style Sheets) are essential tools for building websites. HTML is used to create the structure of a webpage, while CSS is used to style that webpage, making it look visually appealing.

What is HTML?

HTML is the backbone of any website. It uses tags to define elements on a page, such as headings, paragraphs, images, and links. Think of HTML as the skeleton of a body; it gives shape and structure to the content.

Here's a simple example of HTML:

<h1>Hello, World!</h1>
<p>This is a simple webpage.</p>

In this example, <h1> is a tag that creates a heading, and <p> is a tag that creates a paragraph.

What is CSS?

CSS is the language that styles the HTML structure. It controls the layout, colors, fonts, and overall appearance of the webpage. If HTML is the skeleton, CSS is the clothing and accessories that make it look nice.

Here’s a simple example of CSS:

h1 {
    color: blue;
    font-size: 30px;
}

p {
    color: green;
    font-family: Arial, sans-serif;
}

In this example, CSS changes the heading to blue and makes it larger. It also changes the paragraph text to green and sets the font to Arial.

How to Assess Candidates on HTML/CSS

Assessing candidates on their HTML and CSS skills can be done effectively through practical tests that evaluate their knowledge and abilities. Here are two relevant test types you can use:

Take-home projects are another effective way to assess candidates’ skills. Candidates can be given a project brief that requires them to build a webpage or a set of web components. This test allows them to work at their own pace and demonstrate their creativity and technical skills in a real-world scenario. Candidates can submit their work for review, allowing you to evaluate their understanding of HTML and CSS, as well as their ability to follow instructions and meet deadlines.

   HTML is the backbone of any webpage. It provides the structure that organizes content into sections like headers, paragraphs, lists, and images. Each element is defined using HTML tags, which tell the browser how to display the content.

2. Creating Links
   HTML allows you to create hyperlinks that connect different web pages and resources. This interconnectivity is vital for navigation across the web, enabling users to move from one page to another seamlessly.

3. Form Handling
   HTML provides the framework for web forms, which are used to collect user input, such as usernames, passwords, and feedback. Forms are essential for interactive websites, allowing users to engage and share information.

CSS Usage

   CSS is used to enhance the visual appearance of HTML elements. With CSS, you can change colors, fonts, sizes, and layouts, making a website attractive and engaging for users. For instance, you can apply styles to headings, paragraphs, and buttons to ensure a consistent and appealing design.

2. Creating Layouts
   CSS is essential for layout design, allowing developers to organize content effectively on the page. By using techniques like Flexbox and CSS Grid, developers can create responsive layouts that adapt to different screen sizes. This means your website will look great on both desktop and mobile devices.

3. Improving User Experience
