Flexbox Tester · MadebyMike 1. Find the space remaining: The flex container is: 900px The initial size of all the flex items is: (231px + 231px + 231px) = 693px So the space remaining is: 900px - 693px = 207px That's a positive number, so we will be using flex-grow to work out how to distribute the remaining space between the flex items. 2. The total of all flex-grow values is: (1 + 1 + 1) = 3 So 1 flex grow is: 207px/3 = 69px 2. Flex item 1 should be: (1 × 69px) + 231px = 300px Flex item 2 should be: (1 × 69px) + 231px = 300px Flex item 3 should be: (1 × 69px) + 231px = 300px That's a negative number, meaning our items don't fit in the flex container. 2. The total of all scaled flex shrink factors: ( (1 × 231) + (1 × 231) + (1 × 231) ) = 0 The flex-shrink factor for item 1 is: (1 × 231) / 0 = 0 The flex-shrink factor for item 2 is: (1 × 231) / 0 = 0 The flex-shrink factor for item 3 is: (1 × 231) / 0 = 0 3. Flex item 1 should be: (0 × 207px) + 231px = 300px Flex item 2 should be: (0 × 207px) + 231px = 300px
Responsive Web Design just got Easier with the Responsive Grid System Don't use flexbox for overall page layout - JakeArchibald.com When I was building this blog I tried to use flexbox for the overall page layout because I wanted to look cool and modern in front of my peers. However, like all of my other attempts to look cool and modern, it didn't really work. Why? Update: Don't let this post scare you off flexbox, it's one of the best layout systems we have on the web today. Flexbox vs Grid Here's a basic three column design: Here it is mocked up using flexbox (works in all modern browsers), and here it is using grid layout (works in IE10+). Browsers can progressively render content as it's streamed from the server, this is great because it means users can start consuming content before it's all arrived. It's difficult to spot too, you're unlikely to notice it while developing locally, or via a super-fast connection. Flexbox: content dictates layout Here's a simplified version of the layout: As the page loads, the container starts to receive the first child, the main content. But grid can load poorly too...

Rachel Andrew est certainement le plus ardent des promoteurs de CSS Grid Layout. Elle répond ici à la question de savoir quand et comment utiliser Flexbox ou CSS Grid Layout. Par Rachel Andrew Dans ma récente présentation à Fluent Conf, j’ai montré les caractéristiques communes et les différences existant entre Flexbox et CSS Grid Layout. Layout principal vs éléments d’interface utilisateur Quand on découvre CSS Grid Layout, on pense en général qu’il permet de contrôler les grandes division d’une mise en page et fournit un cadre pour les headers, sidebars, contenu principal et footers. Vous pouvez en voir un cas d’usage dans cet exemple. Flexbox n’est pas aussi bien adapté à la création de tels layouts. Nous voyons ici la principale différence entre Flexbox et Grid. Uni-dimensionnel vs bi-dimensionnel Voici l’exemple le plus simple possible de layouts à une et deux dimensions (cliquez sur “Edit on CodePen” pour une version pleine largeur) Flexbox fonctionne comme ça. Intéressé par CSS ?
CSS Flexible Box Layout Module Level 1 Conformance requirements are expressed with a combination of descriptive assertions and RFC 2119 terminology. The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in the normative parts of this document are to be interpreted as described in RFC 2119. However, for readability, these words do not appear in all uppercase letters in this specification. All of the text of this specification is normative except sections explicitly marked as non-normative, examples, and notes. Examples in this specification are introduced with the words “for example” or are set apart from the normative text with class="example", like this: Informative notes begin with the word “Note” and are set apart from the normative text with class="note", like this: Note, this is an informative note. The specification will remain Candidate Recommendation for at least six months.
Grid Designer 2 If you're familiar with the grid, a bit of design and basic typography, using this script should be pretty easy - most of the functions are pretty self-explanatory. If you're unfamiliar with grids in general, you could start by reading an excellent series of articles by web designer Mark Boulton. For those who want a real understanding of the theory of grids in relation to design and typography, I strongly recommend this book. On the Columns tab, you can start your design in two ways: Fill in the number of columns, total width, gutters and margin widths, all specified in pixels - then press the design button. The grid preview on the Columns tab will display the widths of each area, in pixels. Use the Typography tab to adjust and calculate basic typographic settings for your design. Finally, on the Export tab, you can generate copy-and-paste ready CSS, and a sample XHTML template.
