El posicionamiento flotante es el más difícil de comprender pero al mismo tiempo es el más utilizado. La mayoría de estructuras de las páginas web complejas están diseñadas con el posicionamiento flotante, como se verá más adelante. Cuando una caja se posiciona con el modelo de posicionamiento flotante, automáticamente se convierte en una caja flotante , lo que significa que se desplaza hasta la zona más a la izquierda o más a la derecha de la posición en la que originalmente se encontraba. La siguiente imagen muestra el resultado de posicionar de forma flotante hacia la derecha la caja 1: Figura 5.13 Ejemplo de posicionamiento float de una caja Cuando se posiciona una caja de forma flotante: * La caja deja de pertenecer al flujo normal de la página, lo que significa que el resto de cajas ocupan el lugar dejado por la caja flotante. * La caja flotante se posiciona lo más a la izquierda o lo más a la derecha posible de la posición en la que se encontraba originalmente.
Please note: The original technique (FIR) described in the body of this article is no longer recommended for use, as it makes the hidden text completely inaccessible for certain screen readers.

CSS 2.1 is a style sheet language that allows authors and users to attach style (e.g., fonts and spacing) to structured documents (e.g., HTML documents and XML applications). By separating the presentation style of documents from the content of documents, CSS 2.1 simplifies Web authoring and site maintenance. CSS 2.1 builds on CSS2 [CSS2] which builds on CSS1 [CSS1] .
Some have suggested that although the approach of HTML Dog to teach standards-based HTML and CSS without making a song and dance about the standards is perhaps a good one, but by doing so, users (beginners in particular) may come across different approaches and bad practices elsewhere without knowing that there is anything wrong with them. So here's HTML Dog's answer: A guide to what not to use . HTML has attempted to move away from the presentational and towards the meaningful , leading to a philosophy of separating content and meaning (HTML) from presentation (CSS). This general approach tends to lead to much leaner web pages, because a single set of presentational instructions (in an external CSS file) can be applied to many pages.

Some of the 'bad tags' are simply presentational tags (such as small ) that could be replaced with something meaningful or simply with CSS.

Do you really understand them? The name might be a little misleading, because sprites aren't little images like you might be picturing, a sprite is actually one big image . Have you ever seen the CSS technique where the "on" and "off" states of a button are contained within the same image and are activated by shifting the background-position?
