As a vector graphics format, SVG uses precisely-defined geometric shapes
to build an image. But that doesn't mean that SVG graphics have to look
like technical drawings. SVG graphics can be shaded, textured, built
from partially-transparent overlapping layers, or even filled with
photographic images.
SVG Colors, Patterns, and Gradients takes an in-depth look at the
different ways SVG text and shapes can be painted on the screen or page.
Youâ ll start with an overview of how color is defined, including the
various ways you can control the transparency of SVG content. Youâ ll
then dive deep into the concept of an SVG paint server: gradients,
patterns, and other complex graphical content that can be used to
fill-in or outline other SVG shapes and text.
