Online Bootstrap Test (Advance)

Bootstrap does not have a specific form layout called "External form". However, it does provide three other types of form layouts: Vertical form, Inline form, and Horizontal form. These layouts allow developers to easily create and customize forms in their web applications.

Bootstrap was developed by Mark Otto and Jacob Thornton at Twitter, and released as an open source product in August 2011 on GitHub

The answer ".input - lg" suggests that you can size the height of input elements using the class ".input - lg". This class is likely a part of a CSS framework or styling library that provides predefined styles for different sizes of input elements. By applying the ".input - lg" class to an input element, you can increase its height to make it larger than the default size.

The class ".label" is used to provide additional information about something. This class is commonly used in web development to add descriptive text or labels to elements on a webpage. By applying this class to an element, developers can provide additional context or information to users, enhancing the user experience and making the webpage more informative.

The .badge class is not a contextual class because it is used to create a badge or a small notification element. Contextual classes are used to add different colors and styles to elements based on the context or purpose. The other options (.progress-bar-info, .label-primary, .label-success) are contextual classes that are used to style progress bars and labels with specific colors and styles.

The question asks for an example that is not a glyphicon. Glyphicons are a set of icons that are commonly used in web design. The options "Download glyphicon," "Envelope glyphicon," and "Print glyphicon" are all examples of glyphicons because they are icons that represent specific actions or objects. However, the "Menu glyphicon" is not an example of a glyphicon because it represents a menu or a list rather than a specific action or object.

The .well class adds a rounded border around an element with a gray background color and some padding. This class is commonly used to create a visually appealing container or section on a webpage.

To insert plain text to a form label within a horizontal form, the class to use is ".form-control-static". This class is specifically designed for displaying static text within a form control. It ensures that the text is properly aligned and styled within the form.
