CSS: The Missing Manual: Edition 4

The important stuff you need to know:

• Start with the basics. Write CSS-friendly HTML, including the HTML5 tags recognized by today’s browsers.
• Design for mobile devices. Create web pages that look great when visitors use them on the go.
• Make your pages work for you. Add animations that capture the imagination, and forms that get the job done.
• Take control of page layouts. Use professional design techniques such as floats and positioning.
• Make your layouts more flexible. Design websites with Flexbox that adjust to different devices and screen sizes.
• Work more efficiently. Write less CSS code and work with smaller files, using Syntactically Awesome Stylesheets (Sass).
