No need to be explicit when it's obvious
Blue-phrase uses a new technology called symbolic endophrasing, which turns markup syntax inside-out. One of the key features of this smart technology is its ability to imply context.
Implied semantic context starts with the humble but ubiquitous paragraph. In blue-phrase, an explicit paragraph starts with a p semantax, which is equivalent to the HTML <p> tag. In practice, an explicit p is almost never seen, because it is implied. This is how plain text can be considered "blue-phrase" even when no blue-phrase notation is visible.
Consider this starting point, and it's HTML equivalent:
Short phrases that are part of a sentence or paragraph are implied to have a span semantax, which is equivalent to HTML's <span> ... </span> markup, so in this example the word "Tana" could become the target of CSS:
Head and Body
These simple examples omit an important part of HTML: the <html>, <head>, <title>, and <body> tags that are required by the standard. The blue processor examines your source file to see whether or not you've included these, and if not, will provide them for you. So the first example will actually result in HTML like this:
