HTML Editors and Web Browsers
Web pages can be created and modified by using professional HTML editors.
The purpose of a web browser (Chrome, Edge, Firefox, Safari) is to read HTML documents and display them correctly.
HTML Block and Inline Elements
Block-level Elements
A block-level element always starts on a new line, and the browsers automatically add some space (a margin) before and after the element.
A block-level element always takes up the full width available (stretches out to the left and right as far as it can).
Two commonly used block elements are: <p> and <div>.
The <p> element defines a paragraph in an HTML document.
The <div> element defines a division or a section in an HTML document.
The <p> element is a block-level element.
The <div> element is a block-level element.
Inline-level Elements
An inline element does not start on a new line.
An inline element only takes up as much width as necessary.
This is a <span> element inside a paragraph.
<span>Hello World</span>
A block-level element always starts on a new line and takes up the full width available
An inline element does not start on a new line and it only takes up as much width as necessary
The <div> element is a block-level and is often used as a container for other HTML elements
The <span> element is an inline container used to mark up a part of a text, or a part of a document
