Q & A

What is the basic structure of an HTML website?
-The basic structure of an HTML website consists of several key components: DOCTYPE declaration, HTML tags (opening and closing), head section (including title and meta tags), body section (which contains the content of the website), and script tags (for linking JavaScript).
Why do we need to use a basic HTML structure instead of writing content directly?
-The basic structure is essential because it helps organize the content properly within the page. Tags like `<head>`, `<body>`, and `<meta>` help define metadata, structure, and presentation, while allowing proper functionality and SEO optimization.
What is the role of the `<meta>` tag in HTML?
-The `<meta>` tag is used to provide metadata about the HTML document, such as keywords, description, and other meta-information. It is self-closing and provides important details that help search engines and browsers interpret the page.
How can you preview your website on a mobile device while developing it?
-To preview a website on a mobile device, you can use the local IP address of your development machine. By accessing this IP address through the browser on your mobile device (e.g., 192.168.x.x:5000), you can view the live website you're developing.
What is the significance of the title tag in HTML for SEO?
-The title tag is an important element for SEO because it defines the title displayed on the browser tab and is used by search engines to understand the content of the page. A well-written title tag improves page rankings in search engine results.
What is the difference between self-closing and pair tags in HTML?
-Self-closing tags in HTML do not require a closing tag, as they complete their function with just the opening tag (e.g., `<meta>`). Pair tags require both an opening and closing tag (e.g., `<html></html>`, `<body></body>`).
Why does the background change to red when you link a CSS file in HTML?
-The background changes to red because the CSS file contains a rule that sets the background color to red. When the CSS file is linked properly, the styles are applied to the HTML elements, affecting the visual presentation.
How can you speed up the process of web development by using copy-paste techniques?
-Copying and pasting code from trusted sources (e.g., Stack Overflow, other websites) can save time when implementing common elements like forms, buttons, or layout structures. The key is knowing when to copy and when to innovate.
What is the purpose of the lang attribute in HTML?
-The `lang` attribute specifies the language of the content inside an HTML element. For example, `lang='en'` indicates that the content is in English, helping browsers and search engines better interpret and display the content.
What should you do if your website isn't appearing correctly on your mobile device during testing?
-If your website isn't appearing correctly on a mobile device, ensure that your development machine and mobile device are connected to the same network. You may also need to verify the correct IP address and port number to preview the site, and make sure that your network is set to private.
