    Gantry Framework

    Gantry Framework

    Next Generation Template / Theme Framework

    Develop CMS themes quickly and efficiently while providing flexibility and ease of use for end-users. Gantry was born when the RocketTheme development team wanted to consolidate our extensive set of custom Grav, Joomla and WordPress theme functionality into a simple, easy-to-use framework. Yes, that’s right! Gantry 5 has a powerful and easy-to-use Layout Manager that ensures controlling the layout is a highly visual experience. When we started the Gantry 5 project, we wanted to think past the concept of Gantry as a framework. We wanted to create something so versatile and powerful, that it could stand on its own as a platform, virtually independent of a CMS in concept and implementation. Utilizing a dual MIT & GPL license, Gantry is free to use pretty much anywhere! Designed from the ground-up with performance and efficiency in mind. Configure and structure your menu hierarchy with our new Menu editor.

    Jekyll Readme Index

    Jekyll Readme Index

    A Jekyll plugin to render a project's README as the site's index

    A Jekyll plugin to render a project's README as the site's index. Let's say you have a GitHub repository with a README.md file, that you'd like to use as the index (main page) for a GitHub Pages site. You could rename the file to index.md, but then it wouldn't render on GitHub.com. You could add YAML front matter with permalink: / to the README, but why force a human to do what Jekyll can automate? If you have a readme file, and your site doesn't otherwise have an index file, this plugin instructs Jekyll to use the readme as the site's index. That's it, no more, no less.

    Jekyll theme: Adam Blog 2.0

    Jekyll theme: Adam Blog 2.0

    The Minimum Viable Model website and Jekyll theme

    Adam Blog 2.0 is a Jekyll theme that was built to be 100% compatible with GitHub Pages. If you are unfamiliar with GitHub Pages, you can check out their documentation for more information. Jonathan McGlone's guide on creating and hosting a personal site on GitHub is also a good resource. Jekyll is a simple, blog-aware, static site generator for personal, project, or organization sites. Basically, Jekyll takes your page content along with template files and produces a complete website. The beauty of hosting your website on GitHub is that you don't have to actually have Jekyll installed on your computer. Everything can be done through the GitHub code editor, with minimal knowledge of how to use Jekyll or the command line. All you have to do is add your posts to the _posts directory and edit the _config.yml file to change the site settings. With some rudimentary knowledge of HTML and CSS, you can even modify the site to your liking.

    Jekyll::Typogrify

    Jekyll::Typogrify

    A Jekyll plugin that improves the typography of your Liquid templates

    Improves typography on your Jekyll site using typogruby, titlecase, and some other useful functions. Converts an ampersand (ex. &) converts a & surrounded by optional whitespace or a non-breaking space to the HTML entity and surrounds it in a span with a styled class. Surrounds two or more consecutive capital letters, perhaps with interspersed digits and periods in a span with a styled class. Typogruby cap module doesn't support having hyphens so there is a custom module. Converts special characters (excluding HTML tags) to HTML entities. Encloses initial single or double quotes, or their entities (optionally preceded by a block element and perhaps an inline element) with a span that can be styled. Applies smartpants to a given piece of text. Replaces space(s) before the last word (or tag before the last word) before an optional closing element (a, em, span, strong) before a closing tag (p, h[1-6], li, dt, dd) or the end of the string.

    MkDocs Jekyll Theme

    MkDocs Jekyll Theme

    The Material theme from MkDocs provided as a Jekyll template

    This is a starter template for a MkDocs Jekyll theme. GitHub pages uses Jekyll natively, so when I make documentation, I typically look for Jekyll templates. Why? Using Jekyll means that I can use markdown, and allow for users to easily contribute, and build automatically just by way of pushing to a master branch (or general GitHub pages). I’ve liked MkDocs in the past, but it required me to use a special renderer. I also felt limited in my ability to customize it. The same is true for MkDocs material. It’s absolutely gorgeous, but was not suited for my GitHub pages and customization needs. For this reason, I’ve spent some time creating a custom Jekyll template that is (almost) as beautiful and includes all the features that I might want.

    PurifyCSS

    PurifyCSS

    Remove unused CSS. Also works with single-page apps

    A function that takes content (HTML/JS/PHP/etc) and CSS, and returns only the used CSS. PurifyCSS does not modify the original CSS files. You can write to a new file, like minification. If your application is using a CSS framework, this is especially useful as many selectors are often unused. Statically analyzes your code to pick up which selectors are used. The CLI currently does not support file patterns. Remove unused CSS code from your stylesheet. PurifyCSS is meant to be installed via npm and built into your build process using tools like Grunt, Gulp or Webpack. However if you're using a different development stack or building your sites with a CMS like Wordpress, you can use the online tool to clean up your stylesheet. Especially if you are using CSS frameworks like Bootstrap or a multi-purpose Wordpress theme, chances are you are actually using less than 20% of the defined CSS rules.
