    Responsively Lazy

    Responsively Lazy

    Lazy load responsive images

    Lazy load responsive images. The best lazy loading implementation available. Handles responsive images. Truly lazy (absolutely no unnecessary requests) SEO-friendly (valid HTML). It supports WebP. The things to customize are the padding-bottom style and the values of the src and data-srcset attributes. If you don't know the image aspect ratio you can skip the div tag and move the responsively-lazy class to the img tag. Responsively Lazy is very different from the other lazy loading libraries. They make you break your HTML by removing the src attribute, or make you put tiny version there or make you use <noscript> to make your images appear in Google Images. The lazy loading works in browsers supporting the srcset attribute. As of December 2017 that's 86.78%. Unsupported browsers will load the image in the src attribute. That's the image search engines and social networks will find, so it's better to make it high-resolution.

    Turndown

    Turndown

    An HTML to Markdown converter written in JavaScript

    Convert HTML into Markdown with JavaScript. to-markdown has been renamed to Turndown. See the migration guide for details. For usage with RequireJS, UMD versions are located in lib/turndown.umd.js (for Node.js) and lib/turndown.browser.umd.js for browser usage. These files are generated when the npm package is published. To generate them manually, clone this repo and run npm run build. Turndown also accepts DOM nodes as input (either element nodes, document nodes, or document fragment nodes). Options can be passed in to the constructor on instantiation. The key parameter is a unique name for the rule for easy reference. By default, Turndown does not keep any elements. The filter parameter works like a rule filter. To keep elements that are normally handled by rules, add a rule with the desired behaviour.

    html-loader

    html-loader

    HTML Loader

    Exports HTML as a string. HTML is minimized when the compiler demands. The true value enables the processing of all default elements and attributes, the false value disables the processing of all attributes. Allows you to specify which tags and attributes to process, filter them, filter urls and process sources starting with /. Allows to setup which tags and attributes to process and how, as well as the ability to filter some of them. Filter can also be used to extend the supported elements and attributes. By default, the parser in html-loader interprets content inside noscript tags as #text, so processing of content inside this tag will be ignored. A very common scenario is exporting the HTML into their own .html file, to serve them directly instead of injecting with javascript.

Therefore, there is such a component that can conveniently process rich text on the applet platform and also supports rich extension functions.

    Isotope

    Isotope

    Filter and sort layouts

    Include the Isotope .js file in your site. Isotope works on a container element with a group of similar child items. All sizing of items is handled by your CSS. You can use Isotope as a jQuery plugin. You can use Isotope with vanilla JS. You can initialize Isotope in HTML, without writing any JavaScript. All options are optional, but itemSelector is recommended. Layout modes have their own separate options. We recommend always setting itemSelector. itemSelector is useful to exclude sizing elements or other elements that are not part of the layout. If you want to use Isotope to develop commercial sites, themes, projects, and applications, the Commercial license is the appropriate license. With this option, your source code is kept proprietary. If you are creating an open source application under a license compatible with the GNU GPL license v3, you may use Isotope under the terms of the GPLv3.

    flag-icons

    flag-icons

    A curated collection of all country flags in SVG

    A curated collection of all country flags in SVG, plus the CSS for easier integration. For using the flags inline with text add the classes .fi and .fi-xx (where xx is the ISO 3166-1-alpha-2 code of a country) to an empty <span>. If you want to have a squared version flag then add the class fis as well. You could also apply this to any element, but in that case you'll have to use the fib instead of fi and you're set. This means that the flag is just going to appear in the middle of an element, so you will have to set manually the correct size of 4 by 3 ratio or if it's squared add also the flag-icon-squared class. To have only specific countries in the css file, remove the ones that you don't need from the flag-icons-list.less file and build it again.

    jQuery contextMenu plugin & polyfill

    jQuery contextMenu plugin & polyfill

    jQuery contextMenu plugin & polyfill

    The contextMenu Plugin was designed for web applications in need of menus on a possibly large amount of objects. Unlike implementations as a beautiful site's or trendskitchens' this contextMenu treats the menu as the primary object. That means, that a single menu is defined that can be used by multiple objects. Unlike the mentioned plugins, contextMenu doesn't need to bind itself to triggering objects. This allows injecting and removing triggers without having to re-initialize or update contextMenu. contextMenu can provide a simple list of clickable commands, or offer an in-menu form. This makes very simple attribute modification possible. Once a menu is registered, it cannot be altered. That means no commands can be added or removed from the menu. This allows contextMenu to keep a single definition in memory, which enables it to work with hundreds of trigger objects. contextMenu knows the two callbacks show and hide which can be used to update the state of commands within the menu.

    A minimal CSS framework/theme

    Just drop in sakura.css to any webpage and go from ugly looking 1900s website to a pretty modern website in literally 0 seconds. Easy to customize and build on top of sakura. Sakura supports extremely easy theming support using variables for duotone color scheming. Comes with several existing themes, and can be found in the CSS folder of this repository. Don't want to develop using sakura, but instead want to use it on websites with outdated 90's design (i.e. no CSS)? Quick prototyping, especially when working on backend sites and can't yet be bothered to fidget with CSS/HTML. Building a quick (but pretty) site/blog for your best friend or aunt! No need to remember tons of different class names for every other CSS framework. Works amazingly with markdown generated HTML pages (eliminates the need of hacks like including .img img-responsive in markdown-parser generated <img></img> tags).
