This is applied to those elements that CSS considers to be "block" elements, set through the CSS display: block; declaration. HTML also has a similar concept, although different, and the two are very frequently confused. %block; and %inline; are groups within the HTML DTD that group elements as being either "block-level" or "inline".

In the 2010s, the intensive use of popular JavaScript layout frameworks, such as Bootstrap, inspired CSS flex-box and grid layout specifications. [6] CSS modules included solutions akin to this, like Flexbox [2] and grid. [7] Flexbox is originally based on a similar feature available in XUL, the user interface toolkit from Mozilla, used in ...
Marquee can be distracting. [1] The human eye is attracted to movement, [2] and marquee text is constantly moving. As with the blink element, marquee-tagged images or text are not always completely visible on rendered pages, making printing such pages an inefficient (if not impossible) task; typically multiple attempts are required to capture all text that could be displayed where messages ...
To demonstrate specificity Inheritance Inheritance is a key feature in CSS; it relies on the ancestor-descendant relationship to operate. Inheritance is the mechanism by which properties are applied not only to a specified element but also to its descendants. Inheritance relies on the document tree, which is the hierarchy of XHTML elements in a page based on nesting. Descendant elements may ...
{} prevents wraps unless the space is too narrow to display the text on one line. {{inline block}} does the same and allows further style customization, but does not automatically add the "avoidwrap" CSS class. {} produces multiple non-breaking spaces (or a single one).
Another example is the Ajax programming technique, where, for example, clicking a hypertext link may cause JavaScript code to retrieve the text for a new price quotation to display in place of the current one within the page, without re-loading the whole page. When the new text arrives back from the server, the JavaScript must identify the ...
The Cascading Style Sheets (CSS) specification describes how elements of web pages are displayed by graphical browsers. Section 4 of the CSS1 specification defines a "formatting model" that gives block-level elements—such as p and blockquote—a width and height, and three levels of boxes surrounding it: padding, borders, and margins.

The object model provides programmatic access to styles. This means you can change inline styles on individual elements and change style rules using simple JavaScript programming. Inline styles are CSS style assignments that have been applied to an element using the style attribute.
