What techniques can you use to create responsive web graphics?

1 Use vector graphics

Vector graphics are made of mathematical shapes and curves, not pixels. They can scale up or down without losing quality or clarity. They are ideal for logos, icons, diagrams, and illustrations. You can use SVG (Scalable Vector Graphics) format to embed vector graphics in your HTML code, or use CSS properties to create shapes and animations.

2 Optimize raster graphics

Raster graphics are made of pixels, and they can look blurry or pixelated when resized or zoomed. They are suitable for photos, textures, and complex images. You can optimize raster graphics by choosing the right format, compression, and resolution. You can use JPEG for photos, PNG for transparent images, and WEBP for both. You can also use tools like ImageOptim or TinyPNG to reduce the file size and improve the loading speed.

3 Use media queries

Media queries are CSS rules that apply different styles based on the screen size, resolution, orientation, or device type. You can use media queries to change the size, position, alignment, or display of your web graphics according to the viewport. For example, you can use media queries to make your images smaller on mobile devices, or hide them on print media.

4 Use srcset and sizes attributes

Srcset and sizes are HTML attributes that let you specify different versions of the same image for different screen widths. The browser will choose the most appropriate image based on the device pixel ratio and the available space. This way, you can avoid loading large images on small screens, or small images on large screens. For example, you can use srcset and sizes to provide a 300px image for screens up to 600px wide, and a 600px image for screens wider than 600px.

5 Use picture and source elements

Picture and source are HTML elements that let you provide multiple sources of the same image for different scenarios. You can use them to change the image format, aspect ratio, orientation, or content based on the media query. For example, you can use picture and source to provide a WEBP image for browsers that support it, and a JPEG image for browsers that don't. Or you can use them to provide a portrait image for portrait mode, and a landscape image for landscape mode.

6 Use responsive design tools

Responsive design tools are software or online platforms that help you create, test, and preview your web graphics in different devices and scenarios. You can use them to adjust your images, layouts, fonts, colors, and other elements to fit different screen sizes and resolutions. Some examples of responsive design tools are Adobe XD, Figma, Sketch, Bootstrap Studio, and Responsively.
