kódblokk

A kódblokk is a formatting construct used to display computer code in text documents, wikis, and web pages. It preserves line breaks, indentation, and spacing, allowing readers to understand and copy the code accurately. Code blocks differ from inline code, which appears within running text.

Typically there are two main forms: indented code blocks and fenced code blocks. Indented blocks use consistent leading spaces (often four) on each line. Fenced blocks begin with a delimiter such as three backticks or three tildes, end with the same delimiter, and may include a language specifier to request syntax highlighting.

Many markup systems support kódblokkok, including Markdown, reStructuredText, and HTML. In Markdown, the language hint after the opening delimiter enables colorized syntax in supporting editors and viewers. Examples may vary by platform, but the intent is the same: group the enclosed lines as code and prevent their rendering as ordinary text.

Accessibility and best practices include preserving whitespace for readability, avoiding excessive length, and providing clear language hints. When possible, ensure that code blocks are properly tagged for screen readers and that documentation remains legible without visual styling.
