What are viewport units (vw, vh, vmin, vmax)?
Article Introduction：Viewport units are relative units based on browser viewport size in CSS, used to create responsive layouts. 1. vw and vh represent 1% of the viewport width and height respectively. For example, 10vw is 10% of the width and 20vh is 20% of the height, which is suitable for full-screen display or fixed proportional elements; 2. vmin and vmax are calculated based on the smaller or larger edges of the viewport. For example, vmin equals vh and vmax equals vw in landscape screen, which is suitable for adapting to different screen directions; 3. Usage techniques include setting responsive fonts with vw (with media query limit range) and 100vh to implement full-screen blocks, but it is necessary to note that the mobile address bar affects the visual area, which can be solved by 100dvh or JavaScript.
