Each box's left outer edge touches the left edge of the containing block.<br>A block-level element always starts on a new line. In horizontal writing modes, like English or Arabic, it occupies the entire horizontal space of its parent element (container) and vertical space equal to the height of its contents, thereby creating a "block".</p> <div class="notecard note"> <p><strong>Note:</strong> The above behavior of block layout changes if the containing block's <a href="/en-US/docs/Web/CSS/writing-mode"><code>writing-mode</code></a> is set to value other than <a href="/en-US/docs/Web/CSS/writing-mode#formal_definition">the default value</a>.</p> </div> <div class="notecard note"> <p><strong>Note:</strong> HTML (<em>HyperText Markup Language</em>) elements historically were categorized as either "block-level" elements or "inline" elements.
