    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.

    Angular Flex-Layout

    Angular Flex-Layout

    Provides HTML UI layout for Angular applications

    Angular Flex Layout provides a sophisticated layout API using Flexbox CSS + mediaQuery. This module provides Angular developers with component layout features using a custom Layout API, mediaQuery observables, and injected DOM flexbox-2016 CSS stylings. The Flex Layout engine intelligently automates the process of applying appropriate Flexbox CSS to browser view hierarchies. This automation also addresses many of the complexities and workarounds encountered with the traditional, manual, CSS-only application of box CSS. The real power of Flex Layout, however, is its responsive engine. The Responsive API enables developers to easily specify different layouts, sizing, visibilities for different viewport sizes and display devices.

    Balloon.css

    Balloon.css

    Simple tooltips made of pure CSS

    Balloon.css lets you add tooltips to elements without JavaScript and in just a few lines of CSS. By default, tooltips will always remain single-line no matter their length. You can change this behavior by using the attribute data-balloon-length with one of the values, small, medium, large or fit. If for some reason you do not want animations in your tooltips, you can use the data-balloon-blunt attribute for that. If you want to show tooltips even when user interaction isn't happening, you can simply use the data-balloon-visible attribute. The attribute data-balloon-visible can be easily added via JavaScript (e.g. .setAttribute()), enabling you to show tooltips whenever needed. Balloon.css exposes three CSS variables to make it easier to customize tooltips. his way you can use custom CSS to make your own tooltip styles.
