1 - What is the CSS box model? The CSS box model is a way of defining the space around an HTML element. It consists of margins, borders, padding, and the content itself, all of which contribute to the overall dimensions of the element.
2) How do you center an element horizontally in CSS? You can center an element horizontally by setting its margin to ‘auto’ and giving it a specified width. This will ensure that the element is centered within its containing block.
3) What is the difference between ‘display: block’ and ‘display: inline’? Elements with ‘display: block’ take up the full width available, starting on a new line. Elements with ‘display: inline’ take up only as much width as necessary and do not start on a new line, allowing other elements to sit next to them.
4) How can you include a CSS file in another CSS file? You can include a CSS file within another CSS file using the ‘@import’ rule. Simply add ‘@import url("path/to/file.css");’ at the beginning of your CSS file to import the styles.
5) What is the ‘float’ property in CSS? The ‘float’ property in CSS is used to specify whether an element should float to the left, right, or none. Floated elements are taken out of the normal flow of the document and can be positioned next to other content, often used for creating columns in layouts.
6) How do you make text bold in CSS? You can make text bold in CSS by using the ‘font weight’ property and setting it to ‘bold’. This will make the text appear thicker and more prominent.
7) What is the ‘z index’ property in CSS? The ‘z index’ property in CSS is used to control the stacking order of elements on a webpage. Elements with a higher ‘z index’ value will appear on top of elements with a lower value, allowing you to control which elements overlap others.
8) What is a CSS preprocessor? A CSS preprocessor is a tool that extends the functionality of CSS by allowing the use of variables, nesting, mixins, functions, and more. Popular CSS preprocessors include Sass, Less, and Stylus, which help simplify and organize your stylesheets.
9) How do you target an element with a specific class in CSS? You can target an element with a specific class in CSS by using the ‘.’ (dot) followed by the class name. For example, to target an element with the class ‘example’, you would write ‘.example { /* styles here */ }’.
10) How can you create a responsive layout in CSS? You can create a responsive layout in CSS by using media queries to adjust the styling of your elements based on the size of the viewport. By setting different styles for different screen sizes, you can ensure that your layout looks good on various devices.
