CSS3 is the next version of CSS that is modular and supports new features like selectors, colors, fonts, backgrounds, borders and media queries. Some CSS3 modules and features have wider browser support than others. Vendor-specific extensions can be used to implement early stage CSS3, but may require vendor prefixes. JavaScript and CSS polyfills can also be used to enhance browser support. Media queries allow styling content based on characteristics like screen width and height, enabling responsive design.

The document discusses structuring content in a web document and provides objectives for evaluating web accessibility standards, incorporating attributes, implementing the div element, adding HTML5 semantic elements, using special characters, specifying the viewport, validating HTML code, and creating an XHTML document. Key points include making web pages accessible according to WCAG guidelines, using attributes to provide additional information about elements, employing the div element to group related elements, utilizing semantic elements to indicate meaning and improve search results, inserting special characters with references, defining the viewport to control mobile displays, debugging code to fix errors, and validating code to ensure proper rendering and future compatibility.
The document discusses various CSS positioning techniques including the box model, setting widths and borders, margins and padding, floats, clearing flows, and fixed, relative, and absolute positioning. The box model treats elements as boxes with properties for borders, margins, padding, and content. Floats and clearing can be used to create multi-column layouts. Fixed positioning keeps elements visible during scrolling while relative and absolute positioning adjust element locations without and within the normal flow, respectively.
CSS is used to style and lay out HTML elements. CSS rules contain selectors that identify elements and declarations that specify properties and values to style those elements. Different selector types like type, ID, class, and multiple selectors allow rules to target different element groups. Embedded style sheets contain CSS code directly in HTML, while external style sheets can style multiple pages by linking via the <link> element. Comments document style sheets, and developer tools and validators help debug and standardize CSS code.
CSS float digunakan untuk mengatur posisi elemen dengan memaksa elemen tersebut berada di sebelah kiri atau kanan parent elemennya, sehingga dapat memisahkannya dari normal flow. Float umumnya digunakan untuk membuat galeri gambar, layout berkolom, dan text wrapping. Ada beberapa masalah yang mungkin muncul seperti collapsed container, tetapi dapat diselesaikan dengan menggunakan properti clear.
Este documento presenta una introducción a HTML5 y CSS3. Explica que HTML5 incluye nuevos elementos semánticos como <header>, <nav>, <article>, <section> y <footer>. También presenta nuevos elementos multimedia como <video> y <audio>. CSS3 incluye nuevas posibilidades para decoración como fondos múltiples, RGBa, text-shadow, box-shadow y transformaciones.

This document discusses CSS3 features such as selectors, backgrounds and borders, fonts, and media queries. CSS3 is modular and some modules are more complete than others. Browser support for CSS3 varies by feature, though JavaScript can be used to enhance support. New CSS3 selectors like first-child allow targeting elements more precisely. Features like border-radius, multiple backgrounds, opacity, and RGBA color expand styling options. @font-face allows custom web fonts. Media queries permit adaptive designs for different devices.
CSS3 - is everything we used to do wrong? Russ Weakley
The document discusses the benefits and potential issues of using CSS3 and preprocessors. It recommends learning CSS2.1 fundamentals first before jumping into CSS3. Object-oriented CSS, resets, frameworks and preprocessors can make development more efficient and flexible by reducing repetitive code and improving maintenance. However, they also have drawbacks like additional classes and changing mindsets.
