    Firefox GNOME theme

    Firefox GNOME theme

    A GNOME theme for Firefox

    A GNOME theme for Firefox. This theme follows lastest GNOME Adwaita style. Be aware that this theme might do things that are not supported by upstream Firefox. If you face an issue while using this theme, report it here first or test if it is reproducible in vanilla Firefox. If you are a software distribution maintainer, please do not ship these changes by default to your users unless you made it extremely clear that they are using a modified version of Firefox UI. This is a bunch of CSS code to make Firefox look closer to GNOME's native apps. The master branch of this repo supports the current Firefox stable release 105. Theme versions compatible with older Firefox releases are preserved as git tags. We also have the beta branch for fixes only applicable to the current Firefox beta version.

    FitText.js

    FitText.js

    A jQuery plugin for inflating web type

    FitText makes font-sizes flexible. Use this plugin on your fluid or responsive layout to achieve scalable headlines that fill the width of a parent element. Oh, and don't you dare let us catch you using FitText on paragraph text. This is for gigantic display text only! Your text should now fluidly resize, by default: Font-size = 1/10th of the element's width. If your text is resizing poorly, you'll want to turn tweak up/down "The Compressor". It works a little like a guitar amp. The default is 1. This will hopefully give you a level of "control" that might not be pixel perfect, but resizes smoothly & nicely. FitText now allows you to specify two optional pixel values: minFontSize and maxFontSize. Great for situations when you want to preserve hierarchy. Run FitText before anything that hides the element you're trying to size (e.g. before Carousels, Scrollers, Accordions, Tabs, etc). Hiding an element's container removes its width. It can't resize without a width.

    FlexSlider

    FlexSlider

    An awesome, fully responsive jQuery slider plugin

    Simple, semantic markup. Supported in all major browsers, horizontal/vertical slide and fade animations. Multiple slider support, Callback API, and more. Hardware accelerated touch swipe support. Custom navigation options, compatible with the latest version of jQuery. Display your products in a neatly designed, responsive slideshow within WooCommerce. FlexSlider was built to serve up the best responsive jQuery slider around. I had built a few implementations of responsive sliders on different client projects and noticed that there was a glaring hole for plugin support with the concept. I wanted to build a plugin that would serve the newest of beginners, while providing seasoned developers a tool they could use with confidence. What has come forth is this, FlexSlider. I plan to maintain this plugin and provide support to users implementing FlexSlider into their sites. Responsive web design can be tricky, but I hope that FlexSlider serves to uncomplicate the process, just a little bit.
