Is there something in JavaScript similar to @import in CSS that allows you to include a JavaScript file inside another JavaScript file?

Web developer guides. These articles provide how-to information to help you make use of specific technologies and APIs.

Modernizr est voué à la détection des fonctionnalités navigateurs via JavaScript. Il permet de prévoir des alternatives (basées sur d'autres bibliothèques) pour les moteurs ne supportant pas l'une ou l'autre des propriétés CSS, HTML, etc.

The recipe for the best user experience: Start with POSH, a simple set of heading/div pairs Add ARIA (role, aria-selected, aria-hidden, aria-labelledby) and tabindex attributes using JavaScript as these would be confusing if there was no behavior attached to the widgets. Use JavaScript to also plug a class on the component according to its type (accordion or tabpanel). Style the widget using the selector inserted by the script, this way containers are not hidden if there is no script support. Use cursor to style the tabs because those behave like buttons (default), not links (pointer). In case the component is displayed as a Tab Panel, style it as an Accordion before its tabs start wrapping (to accomodate user’s font-size) or at narrow widths...... ../..

The reason this is bad is that the CSS will hide the iframe no matter what and users with JavaScript turned off will never see that iframe. Now I'm not usually one to go to extreme lengths to cater to that crowd, but I'm all for using better solutions that do solve that issue when they are available.

For the past three years, I've done a lot of research and experiments related to the idea of style scoping and element queries in CSS. Since experimenting with element queries, I've noticed a big transformation in how I write HTML, and the fine-grained nature of element queries has improved the way I write CSS too. In this article I am going to explain why I love Element Queries and how you can get started easily.

Is it possible to set the equivalent of a src attribute of an img tag in CSS?

No. Once a script is loaded, the objects and functions it defines are kept in memory. Removing a script element does not remove the objects it defines. This is in contrast to CSS files, where removing the element does remove the styles it defines. That's because the new styles can easily be reflowed. Can you imagine how hard it would be to work out what a script tag created and how to remove it? EDIT: However, if you have a file that defines myFunction, then you add another script that redefines myFunction to something else, the new value will be kept. You can remove the old script tag if you want to keep the DOM clean, but that's all removing it does. EDIT2: The only real way to "clean up" functions that I can think of is to have a JS file that basically calls delete window.myFunction for every possible object and function your other script files may define. For obvious reasons, this is a really bad idea.

Le sélecteur jQuery est la plupart du temps utilisé pour sélectionner des éléments existant dans le DOM, via une règle CSS. Mais le sélecteur peut aussi créer de nouveaux éléments HTML de manière extrêmement simple ! Voici un petit exemple très simple qui créé un élément div , écrit "Salut !" à l'intérieur, puis enfin ajoute cet élément à la fin de la page web (en l'ajoutant à la fin body) :

There are a bunch of techniques going around for dealing with responsive images lately. That is, solutions to help us serve the right image for the occasion (e.g. size of screen and bandwidth available). They all do things a bit differently. To keep track, Christopher Schmitt and I have created this spreadsheet of techniques.

What is this all about? The goal of this technique is to deliver optimized, contextual image sizes for responsive layouts that utilize dramatically different image sizes at different resolutions. Ideally, this approach will allow developers to start with mobile-optimized images in their HTML and specify a larger size to be used for users with larger screen resolutions — without requesting both image sizes, and without UA sniffing.

Lazy Load is delays loading of images in long web pages. Images outside of viewport are not loaded until user scrolls to them. This is opposite of image preloading. Using Lazy Load on long web pages will make the page load faster. In some cases it can also help to reduce server load.
