Responsive Web Design

Responsive web design is a CSS approach that ensures websites display properly on any screen size, with "Mobile First Design" being the most popular technique. The method involves using a viewport meta tag and CSS media queries to apply different styles based on screen width, such as changing text color or hiding/showing elements at specific breakpoints. One common implementation overrides base styles with media queries for progressively smaller screens, like setting a class to red by default, then orange for screens under 500px, blue under 300px, and yellow under 100px.

Responsive web design is a web design or CSS style that makes a website look good on any screen size. Note: The most popular responsive design technique is "Mobile First Design". To make the page optimized for mobile devices, first use this meta tag in the "head" Сode: <meta name="viewport" content="width=device-width, initial-scale=1" / @media max-width: 500px { p { color: red; } } @media min-width: 500px { p { color: blue; } } img { max-width:100%; height: auto; display: inline-block; } .wrapper { width: 100%; max-width: 560px; margin: 0 auto; } @media width = 500px { p { color: red; } } @media width <= 500px { p { color: green; } } or @media width = 500px { .mobileVersion { display: none; } .desktopVersion { display: block; color: red } } @media width <= 500px { .mobileVersion { display: block; color: green; } .desktopVersion { display: none; } } I write CSS styles simultaneously for any screen, my method is the method of overriding the style above with the style below hierarchy in CSS , for example, there is a regular style for large screens: .testClass { color: red; } Then under it I add the same CSS class and properties from the style above with values for other screens using CSS Media Queries: .testClass { color: red; } @media max-width: 500px { .testClass { color: orange; } } @media max-width: 300px { .testClass { color: blue; } } @media max-width: 100px { .testClass { color: yellow; } } so I override the style above and create a new style with overriding method for screens that are not larger than 500 pixels, then for 200px with overwriting , then for 100px etc Doc:
