Mastering SVG

By: Rob Larsen

Overview of this book

SVG is the most powerful image format in use on the web. In addition to producing resolution-independent images for today's multi-device world, SVG allows you to create animations and visualizations to add to your sites and applications. The simplicity of cross-platform markup, mixed with familiar modern web languages, such as CSS and JavaScript, creates a winning combination for designers and developers alike. In this book, you will learn how to author an SVG document using common SVG features, such as elements and attributes, and serve SVG on the web using simple configuration tips for common web servers. You will also use SVG elements and images in HTML documents. Further, you will use SVG images for a variety of common tasks, such as manipulating SVG elements, adding animations using CSS, mastering the basic JavaScript SVG (API) using Document Object Model (DOM) methods, and interfacing SVG with common libraries and frameworks, such as React, jQuery, and Angular. You will then build an understanding of the Snap.svg and SVG.js APIs, along with the basics of D3, and take a look at how to implement interesting visualizations using the library. By the end of the book, you will have mastered creating animations with SVG.

More on fills and strokes

You've seen them in use in most of the examples, now let's take a little bit of a more complete look at fills and strokes. These presentation attributes are important to SVG, especially when working with them dynamically, as it's much easier to manipulate elements directly as compared to writing dynamic CSS.

fill and stroke are collectively referred to as paint properties. fill sets the inside color of the object and stroke sets the color of the line drawn around the object. As you've already seen, they can accept any valid CSS color value. They can also accept a reference to a paint server element (these are hatch, linearGradient, meshgradient, pattern, radialGradient, and solidcolor), which are elements that define a paint style for the element. You've already seen one of these (linearGradient) and will learn about the more commonly supported ones shortly. Before you do, however, it's time to take a look at some stroke-specific attributes that control the way the...
