Solved by Flexbox — Cleaner, hack-free CSS
All of the code samples on this site show how to solve a particular design problem with Flexbox. They show just the code that's needed to make the demos work in a spec-compliant browser. Some browsers do not fully comply with the latest version of the spec, so sadly, a few workarounds were necessary. Workarounds for non-compliant browsers are not shown in the code samples, but if you're curious about those implementation details, you can check out the source files. The vendor prefixing and translating of current flex properties to their legacy equivalents is all handled by autoprefixer. The class naming convention used in the code samples and source files is taken from SUIT CSS, which is based on BEM methodologies. If you find a mistake or would like to suggest an additional example, feel free to open an issue or submit a pull request on Github.
Sass Basics
Before you can use Sass, you need to set it up on your project. If you want to just browse here, go ahead, but we recommend you go install Sass first. Go here if you want to learn how to get everything set up. PreprocessingPreprocessing permalink CSS on its own can be fun, but stylesheets are getting larger, more complex, and harder to maintain. This is where a preprocessor can help. Once you start tinkering with Sass, it will take your preprocessed Sass file and save it as a normal CSS file that you can use in your website. The most direct way to make this happen is in your terminal. You can also watch individual files or directories with the --watch flag. sass --watch input.scss output.css You can watch and output to directories by using folder paths as your input and output, and separating them with a colon. sass --watch app/sass:public/stylesheets Sass would watch all files in the app/sass folder for changes, and compile CSS to the public/stylesheets folder. 💡 Fun fact: SCSS Syntax
Le modèle tabulaire en CSS
Le modèle de construction tabulaire (HTML et CSS) compte sans aucun doute parmi les plus fascinants qui soient, après avoir été d'abord adulé puis banni vigoureusement par les intégrateurs de tous poils. En 1998, les spécifications CSS2 étendent les historiques valeurs de la propriété display et proposent depuis belle lurette des possibilités de rendus et positionnements “tabulaires” sans pour autant interférer dans la sémantique et le bon usage des éléments HTML. Passons immédiatement à table et découvrons en détail le monde mal connu du Modèle Tabulaire en CSS… Note : Cet article est publié conjointement sur OpenWeb.eu.org et sur Alsacreations.com. En outre, certaines parties de cet article sont extraites du livre “CSS avancées, vers HTML5 et CSS3”, avec l’aimable autorisation de l’auteur :) Compatibilité Tableau des compatibilités Display Depuis les spécifications CSS2, pas moins de 10 valeurs dédiées aux rendus tabulaires ont été ajoutées à la propriété display. table inline-table table-row

Flexbox browser support Three versions of the flexbox spec – each with different syntax – have been implemented in browsers. The two 2012 specs are roughly equivilant in terms of features, differing mainly in syntax. The earlier 2009 spec is less comprehensive though covers a lot of the same ground. Flexbox 2012 — W3C Candidate Recommendation, September 2012 Opera 12.1+, Firefox 22+. More browser support info available on caniuse.com. Known issues Flexbox early 2012 Flexbox early 2012 (Internet Explorer 10) align-content (equiv. flex-line-pack) doesn't work if the cross axis dimension is set with min-width or min-height Flexbox 2009 Box wrapping is not supported. box-lines is the property in this spec to achieve wrapping, though unfortunately no browser implemented it. Flexbox 2009 (Firefox) Firefox has a number of non-trivial issues with its 2009 implementation: The setting display: box is treated as display: inline-box if there is no width set.

Comprendre l'héritage et la parenté des styles CSS
Les styles CSS fonctionnent sur le principe d'imbrication, de parenté et d'héritage, quelques explications. Le modèle Parent-Enfant(s) L'héritage des CSS est fondé sur le modèle Parent-Enfant(s) : chaque élément Enfant reçoit en héritage tous les styles de son élément Parent. Par exemple, la balise <html> est parent de <body>, et <table> est parent de <tr> qui lui-même est parent de <td>. Cet héritage est très pratique et permet d'éviter beaucoup de répétitions inutiles : en effet, en attribuant une propriété à un parent (par exemple font-size: 1.5em), elle sera transmise à tous ses enfants, mais aussi aux enfants de ces enfants, etc... Précision : l'élément enfant héritera de toutes les propriétés de l'élément parent uniquement si ces propriétés s'héritent, car l'héritage ne fonctionne pas non plus sur toutes les propriétés css (margin, padding et autres propriétés de bloc) Voici un exemple illustrant bien ce principe d'héritage. Le code HTML : <body> test <div>test</div></body> Exemple 1 :
CSS Reference: Box Model
XHTML documents contain elements (tags) that are organized into a hierarchy. Web browsers use CSS to lay out the contents of the elements and to give the contents visual formatting. A Web browser draws a rectangle for each element represented on a Web page, and lays out rectangles on the page as shown in the illustration below. The rendering of elements as rectangles in this way is called the "Box Model", since each element is rendered as a box. The CSS determines the characteristics of each box (its placement on the page, colors, border, etc., plus the font and style used for its contents). Boxes or rectangles drawn to represent elements are made up of 4 parts. There are two types of elements - block and inline: Block elements Block elements take up 100% of the width of their parent element. Inline elements Inline elements take up only the width of their contents. CSS control the appearance of each rectangle and its contents.
