1 - What is the difference between display: none and visibility: hidden in CSS?
display: none removes the element from the document flow completely, making it not render on the page and taking up no space. visibility: hidden hides the element while still taking up space in the document flow.
2) How do you center an element horizontally and vertically in CSS?
To center an element horizontally, you can set margin left and margin right to auto, and for vertical centering, you can use flexbox or grid layout with align items and justify content set to center.
3) Explain the box model in CSS.
The box model in CSS consists of content, padding, border, and margin. The content is the actual element content, padding is the space between the content and its border, border is the element's boundary, and margin is the space outside the border.
4) What are pseudo classes and pseudo elements in CSS?
Pseudo classes are used to define the special state of an element such as :hover for mouseover effect, while pseudo elements are used to style a specific part of an element, like ::before or ::after to add content before or after an element.
5) How can you optimize a website's performance?
To optimize website performance, you can minify and concatenate CSS and JavaScript files, enable caching, optimize images, reduce server response time, use a content delivery network (CDN), and eliminate render blocking resources.
6) What is semantic HTML?
Semantic HTML is using HTML elements that have meaning beyond their presentation, such as <header> for the top section of a page, <footer> for the bottom section, <nav> for navigation links, and <article> for a standalone piece of content.
7) How do you include a CSS file in an HTML document?
To include a CSS file in an HTML document, you can use the <link> tag in the <head> section of the HTML file with the href attribute pointing to the CSS file.
8) Explain the differences between inline, block, and inline block elements in HTML.
Inline elements do not start on a new line and only take up as much width as necessary. Block elements start on a new line and take up the full width available. Inline block elements are similar to inline elements but retain the ability to set a width and height.
