  1. What is HTML?

    HTML stands for HyperText Markup Language. It is a markup language used to create web pages and web applications. HTML uses tags to define the structure and content of a web page, such as headings, paragraphs, images, links, lists, and more.

  2. What are the basic tags in HTML?

    Some of the basic HTML tags include:

    • <html>: Defines the root element of an HTML document.

    • <head>: Contains meta-information about the HTML document, such as the title, character encoding, and CSS styles.

    • <body>: Contains the visible content of the web page.

    • <h1> to <h6>: Define headings with different levels of importance.

    • <p>: Represents a paragraph.

    • <a>: Creates a hyperlink.

    • <img>: Embeds an image on the web page.

    • <ul> and <ol>: Create unordered and ordered lists, respectively.

    • <li>: Defines a list item.

  1. What is the difference between <div> and <span> in HTML?

    <div> and <span> are both container elements in HTML, but they are used in different contexts. The main difference is that <div> is a block-level element, while <span> is an inline element. This means that <div> creates a block-level element that takes up the entire width of its parent element, while <span> creates an inline element that only takes up the space it needs within its parent element.

  2. What is a "doctype" in HTML and why is it important?

    A doctype declaration (<!DOCTYPE>) is used to specify the version of HTML or XHTML that a web page is written in. It is important because it informs the web browser about the version of HTML being used on the page, which helps the browser to render the page correctly. Different versions of HTML have different syntax and features, so specifying the correct doctype is essential for ensuring proper rendering and functionality of web pages.

  3. What are some semantic HTML elements and why are they important?

    Semantic HTML elements are used to convey the meaning or purpose of the content they contain, making the HTML code more descriptive and meaningful. Some examples of semantic HTML elements include <header>, <nav>, <aside>, <main>, <article>, <section>, <footer>, <figure>, <figcaption>, and more. They are important because they improve the accessibility and SEO (Search Engine Optimization) of web pages, and help in creating a well-structured and maintainable codebase.

  4. What is the purpose of the "alt" attribute in the <img> tag?

    The "alt" attribute in the <img> tag is used to provide alternative text for an image. It is displayed when the image cannot be loaded or when the user is using a screen reader to access the web page. The "alt" attribute is also used by search engines to index images, and it is considered good practice to provide descriptive and meaningful alternative text to improve accessibility and SEO.

  5. To create a hyperlink in HTML, you can use the <a> tag, like this:

     <a href="https://www.example.com">Click here</a>

    The "href" attribute specifies the URL (Uniform Resource Locator) that the hyperlink points to. The text between the <a> tags is the visible link text that users can click on.

  6. How can you add comments in HTML?

    In HTML, you can add comments using the <!-- --> syntax. For example:

     <!-- This is a comment in HTML

  7. What is the difference between <input type="text"> and <input type="password"> in HTML?

    <input type="text"> and <input type="password"> are both input elements used to accept user input in HTML forms, but they differ in how the input is displayed. <input type="text"> displays the input text in plain text format, while <input type="password"> masks the input text with asterisks or dots to hide it from being visible on the screen. <input type="password"> is commonly used for accepting sensitive information like passwords to protect user privacy.

  8. How can you include external CSS styles in an HTML document?

    You can include external CSS (Cascading Style Sheets) styles in an HTML document by using the <link> tag. Here's an example:

    <link rel="stylesheet" href="styles.css">

    The rel attribute specifies the relationship between the HTML document and the linked file, which should be set to "stylesheet" for CSS files. The href attribute specifies the URL of the external CSS file. By linking an external CSS file to an HTML document, you can separate the styles from the HTML code, making it easier to maintain and update the styles across multiple web pages.
