CSS Flexible Box Layout Module

CSS Flexible Box Layout Module
Abstract The specification describes a CSS box model optimized for user interface design. In the flex layout model, the children of a flex container can be laid out in any direction, and can “flex” their sizes, either growing to fill unused space or shrinking to avoid overflowing the parent. Both horizontal and vertical alignment of the children can be easily manipulated. Nesting of these boxes (horizontal inside vertical, or vertical inside horizontal) can be used to build layouts in two dimensions. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. Status of this document This section describes the status of this document at the time of its publication.

CSS Grid Template Layout Module Abstract Above: a typical Web page. Below: the underlying grid template. CSS is a simple, declarative language for creating style sheets that specify the rendering of HTML and other structured documents. The ‘grid’ property sets up a matrix of rows and columns and designates empty areas and areas for content (called “slots”). The ‘::slot()’ pseudo-element allows to style the slots (backgrounds, borders, etc.) Grid templates can also be associated with pages in paged media, to create page templates. Slots can form “chains” to create non-rectangular regions. The ‘@region’ rule [CSS3-REGIONS] allows to select (parts of) elements based on whether they fall in a certain slot or not, and thus style content differently in different slots (region-based styling).

filamentgroup/Southstreet A Complete Guide to Flexbox Background The Flexbox Layout (Flexible Box) module (a W3C Candidate Recommendation as of October 2017) aims at providing a more efficient way to lay out, align and distribute space among items in a container, even when their size is unknown and/or dynamic (thus the word "flex"). The main idea behind the flex layout is to give the container the ability to alter its items' width/height (and order) to best fill the available space (mostly to accommodate to all kind of display devices and screen sizes). A flex container expands items to fill available free space, or shrinks them to prevent overflow. Most importantly, the flexbox layout is direction-agnostic as opposed to the regular layouts (block which is vertically-based and inline which is horizontally-based). Note: Flexbox layout is most appropriate to the components of an application, and small-scale layouts, while the Grid layout is intended for larger scale layouts.

A Guide to Mobile Emulators In a previous article, I put forward a three-point plan for testing mobile Web sites. One of the points involved the use of emulators for first-pass device testing. This article concentrates on configuring emulators for mobile site testing (it also highlights emulators that can be used to test mobile applications too). It outlines the different types of emulator available, the best ones to use, and the various ways in which they can be used. For the uninitiated, an emulator is a software program that aims to replicate the functions of a specific piece of hardware or software. About Device-Specific Testing Desktop Web developers have it relatively easy – build in support for four or five browsers, and it’s job done. The simple answer is – you can’t. Types of Mobile Emulator Mobile emulators fall into three main categories: Device emulators - These are generally provided by device manufacturers and simulate the actual device.

The CSS 3 Flexible Box Model This article about the Flexible Box Layout was written by Jérémie Patonnier, French open Web enthusiast. The flexible box model CSS 3 introduces a brand new box model in addition of the traditional box model from CSS 1 and 2. The flexible box model determines the way boxes are distributed inside other boxes and the way they share the available space. You can see the specification here. This box model is similar to the one used by XUL (the user interface language used by Firefox). Usually the flexible box model is exactly what you need if you want to create fluid layouts which adapt themselves to the size of the browser window or elastic layouts which adapt themselves to the font size. In this article, all my examples are based on the following HTML code: Distributing boxes: so what? By default, the traditional CSS box model distributes boxes vertically depending on the HTML flow. Horizontal or vertical distribution Reversed distribution Explicit distribution And what about flexibility? Box sizing

Overthrow: An overflow polyfill for responsive design Posted by Scott on 02/22/2012 Topics: accessibility css javascript mobile responsive design We’ve come to take the CSS overflow property for granted when designing websites for desktop browsers. But overflow support among mobile devices is spotty: some browsers support it, but many popular ones at best require 2-finger gestures to scroll the content, and at worst treat the content the same as overflow: hidden, making it inaccessible to users. So we set out to build a solution that smoothes the way. Overthrow Project Site For cross-device overflow, no perfect solutions Overflow support is gaining rapidly in newer versions of mobile browsers. This leaves us with a dilemma. First, we looked to a number of popular open-source projects that bring overflow support to touch devices to see whether any would satisfy our requirements. Most importantly, we wanted an approach that is designed to slowly kill itself off, allowing native implementations to do their thing as support becomes better and better.

CSS Device Adaptation Abstract This specification provides a way for an author to specify, in CSS, the size, zoom factor, and orientation of the viewport that is used as the base for the initial containing block. Status of this document This is a public copy of the editors' draft. It is provided for discussion only and may change at any moment. The (archived) public mailing list (see instructions) is preferred for discussion of this specification. This document was produced by the CSS Working Group (part of the Style Activity). This document was produced by a group operating under the 5 February 2004 W3C Patent Policy. Table of Contents 1. This section is not normative. CSS 2.1 [CSS21] specifies an initial containing block for continuous media that has the dimensions of the viewport. The narrow viewport is a problem for documents designed to look good in desktop browsers. 2. This specification follows the CSS property definition conventions from [CSS3SYN]. Value types are defined in [CSS3VAL].
