Go language tutorial manual

Course Elementary 27448

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.

CSS drop cap image, text aligned in white space

I don't think this is an everyday dropcap situation. My capital "S" is an image like this: Note that the actual image extends all the way to the upper column.

The image provided to me looks like this - a rectangular area with a top bar drawn in the upper right corner and white space below the top bar. I want the text to look like this (
