Responsive Images

Lesson 1 - Getting up and Running

Before you start working with responsive images, you need to start debugging on your mobile devices. This lesson will help you get started with Developer Tools and mobile debugging.

Lesson 2 - Units, Formats, Environments

You can't optimize what you can't measure. In this lesson, you will start with comparing different kinds of images on the web and getting familiar with different units you can use to scale them. You will also get a chance to set up your development environment so that responsive images become a painless part of your workflow. At the end of the lesson, you will start working on the responsive blog project, where you have a chance to apply responsive image principles in a real-world scenario! Topics covered: * Sizing Images * File Types * Automation Tools

Lesson 3 - Images with Markup

Not all graphics need to be .JPGs or .PNGs. This lesson dives into using markup techniques like CSS and icon fonts to create responsive graphics. While markup techniques are awesome because they are natively responsive, they are often **extremely** lightweight, requiring a fraction of the bytes of traditional images! At the end of the lesson, you will replace extraneous images with markup techniques and take advantage of font icons to add social media icons to the responsive blog project! Topics covered: * CSS Techniques * Inlining Images * Unicode * Icon fonts

Lesson 4 - Full Responsiveness

Here comes the full monty! In this lesson, you will make your images fully responsive using the new `` element! Along the way, you will use the `srcset` and `sizes` attributes. You will also learn the importance of `alt` attributes for your visually impaired users. At the end of this lesson, you will make the blog project fully responsive, as you implement `` to display beautiful images across a range of device widths and pixel ratios. Topics covered: * `` * `sizes` attribute * `srcset` attribute * `alt` attributes
