+{%- comment -%}
+This file can be used to fix the HTML produced by Jekyll for highlighted
+code with line numbers.
+
+It works with `{% highlight some_language linenos %}...{% endhighlight %}`
+and with the Kramdown option to add line numbers to fenced code.
+
+The implementation was derived from the workaround provided by 
+Dmitry Hrabrov (DeXP) at
+https://github.com/penibelst/jekyll-compress-html/issues/71#issuecomment-188144901
+
+EXPLANATION
+
+The HTML produced by Rouge highlighting with lie numbers is of the form
+`code table`. Jekyll (<= 4.1.1) always wraps the highlighted HTML
+with `pre`. This wrapping is not only unnecessary, but also transforms
+the conforming HTML produced by Rouge to non-conforming HTML, which
+results in HTML validation error reports. 
+
+The fix removes the outer `pre` tags whenever they contain the pattern
+`<table class="rouge-table">`.
+  
+Apart from avoiding HTML validation errors, the fix allows the use of
+the [Jekyll layout for compressing HTML](http://jch.penibelst.de),
+which relies on `pre` tags not being nested, according to
+https://github.com/penibelst/jekyll-compress-html/issues/71#issuecomment-172069842 
+
+USAGE
+
+(Any names can be used for `some_var` and `some_language`.)
+
+{% capture some_var %}
+{% highlight some_language linenos %}
+Some code
+{% endhighlight %}
+{% endcapture %}
+{% include fix_linenos.html code=some_var %}
+
+For code fences:
+
+{% capture some_var %}
+```some_language
+Some code
+```
+{% endcapture %}
+{% assign some_var = some_var | markdownify %}
+{% include fix_linenos.html code=some_var %}
+
+CAVEATS
+
+The above does not work when `Some code` happens to contain the matched string 
+`<table class="rouge-table">`.
+
+The use of this file overwrites the variable `fix_linenos_code` with `nil`.
+
+{%- endcomment -%}
+
+{% assign fix_linenos_code = include.code %}
+{% if fix_linenos_code contains '<table class="rouge-table">' %}
+  {% assign fix_linenos_code = fix_linenos_code | replace: '<pre class="highlight">', '<pre>' %}

+    The values of `title` and `nav_order` can be numbers or strings.
+    Jekyll gives build failures when sorting on mixtures of different types,
+    so numbers and strings need to be sorted separately.
+
+    Here, numbers are sorted by their values, and come before all strings.
+    An omitted `nav_order` value is equivalent to the page's `title` value
+    (except that a numerical `title` value is treated as a string).
+
+    The case-sensitivity of string sorting is determined by `site.nav_sort`.

+    Version 1.0.7
+      https://github.com/allejo/jekyll-anchor-headings
+
+    "Be the pull request you wish to see in the world." ~Ben Balter
+
+    Usage:
+      {% include anchor_headings.html html=content anchorBody="#" %}
+
+    Parameters:
+      * html          (string) - the HTML of compiled markdown generated by kramdown in Jekyll
+
+    Optional Parameters:
+      * beforeHeading (bool)   : false  - Set to true if the anchor should be placed _before_ the heading's content
+      * anchorAttrs   (string) :  ''    - Any custom HTML attributes that will be added to the `<a>` tag; you may NOT use `href`, `class` or `title`;
+                                          the `%heading%` and `%html_id%` placeholders are available
+      * anchorBody    (string) :  ''    - The content that will be placed inside the anchor; the `%heading%` placeholder is available
+      * anchorClass   (string) :  ''    - The class(es) that will be used for each anchor. Separate multiple classes with a space
+      * anchorTitle   (string) :  ''    - The `title` attribute that will be used for anchors
+      * h_min         (int)    :  1     - The minimum header level to build an anchor for; any header lower than this value will be ignored
+      * h_max         (int)    :  6     - The maximum header level to build an anchor for; any header greater than this value will be ignored
+      * bodyPrefix    (string) :  ''    - Anything that should be inserted inside of the heading tag _before_ its anchor and content
+      * bodySuffix    (string) :  ''    - Anything that should be inserted inside of the heading tag _after_ its anchor and content
+
+    Output:
+      The original HTML with the addition of anchors inside of all of the h1-h6 headings.

+# normalize.scss
 
-Normalize.scss is the SCSS version of [normalize.css](http://necolas.github.io/normalize.css), a customisable CSS file that makes browsers render all elements more consistently and in line with modern standards.
+Normalize.scss is an SCSS copy of [normalize.css](http://necolas.github.io/normalize.css), a customisable CSS file that makes browsers render all elements more consistently and in line with modern standards.
+
+The [normalize.scss fork](https://github.com/guerrero/normalize.scss) of [normalize.css](http://necolas.github.io/normalize.css) was archived in 2014, and has not been updated since v0.1.0.
 
 [View the normalize.css test file](http://necolas.github.io/normalize.css/latest/test.html)
-
-## Install
-
-* [npm](http://npmjs.org/): `npm install --save normalize.scss`
-* [Component(1)](https://github.com/component/component/): `component install guerrero/normalize.scss`
-* [Bower](http://bower.io/): `bower install --save normalize.scss`
-* Download: Go to [this link](https://raw.githubusercontent.com/guerrero/normalize.scss/master/normalize.scss), press right-click on the page and choose "Save as..."
-
-No other styles should come before Normalize.scss.
-
-It's recommendable to modify `normalize.scss` to suit it to your project
-
-## What does it do?
-
-* Preserves useful defaults, unlike many CSS resets.
-* Normalizes styles for a wide range of elements.
-* Corrects bugs and common browser inconsistencies.
-* Improves usability with subtle improvements.
-* Explains what code does using detailed comments.
-
-## Browser support
-
-* Google Chrome (latest)
-* Mozilla Firefox (latest)
-* Mozilla Firefox 4
-* Opera (latest)
-* Apple Safari 6+
-* Internet Explorer 8+
-
-[Normalize.css v1 provides legacy browser
-support](https://github.com/necolas/normalize.css/tree/v1) (IE 6+, Safari 4+),
-but is no longer actively developed.
-
-## Extended details
-
-Additional detail and explanation of the esoteric parts of normalize.css.
-
-#### `pre, code, kbd, samp`
-
-The `font-family: monospace, monospace` hack fixes the inheritance and scaling
-of font-size for preformated text. The duplication of `monospace` is
-intentional.  [Source](http://en.wikipedia.org/wiki/User:Davidgothberg/Test59).
-
-#### `sub, sup`
-
-Normally, using `sub` or `sup` affects the line-box height of text in all
-browsers. [Source](http://gist.github.com/413930).
-
-#### `svg:not(:root)`
-
-Adding `overflow: hidden` fixes IE9's SVG rendering. Earlier versions of IE
-don't support SVG, so we can safely use the `:not()` and `:root` selectors that
-modern browsers use in the default UA stylesheets to apply this style. [SVG
-Mailing List discussion](http://lists.w3.org/Archives/Public/public-svg-wg/2008JulSep/0339.html)
-
-#### `input[type="search"]`
-
-The search input is not fully stylable by default. In Chrome and Safari on
-OSX/iOS you can't control `font`, `padding`, `border`, or `background`. In
-Chrome and Safari on Windows you can't control `border` properly. It will apply
-`border-width` but will only show a border color (which cannot be controlled)
-for the outer 1px of that border. Applying `-webkit-appearance: textfield`
-addresses these issues without removing the benefits of search inputs (e.g.
-showing past searches).
-
-#### `legend`
-
-Adding `border: 0` corrects an IE 8–11 bug where `color` (yes, `color`) is not
-inherited by `legend`.

+
+## Document collections
+
+By default, the navigation and search include normal [pages](https://jekyllrb.com/docs/pages/).
+Instead, you can also use [Jekyll collections](https://jekyllrb.com/docs/collections/) which group documents semantically together.
+
+For example, put all your documentation files in the `_docs` folder and create the `docs` collection:
+```yaml
+# Define Jekyll collections
+collections:
+  # Define a collection named "docs", its documents reside in the "_docs" directory
+  docs:
+    permalink: "/:collection/:path/"
+    output: true
+
+just_the_docs:
+  # Define which collections are used in just-the-docs
+  collections:
+    # Reference the "docs" collection
+    docs:
+      # Give the collection a name
+      name: Documentation
+      # Exclude the collection from the navigation
+      # Supports true or false (default)
+      nav_exclude: false
+      # Exclude the collection from the search
+      # Supports true or false (default)
+      search_exclude: false
+```
+
+You can reference multiple collections.
+This creates categories in the navigation with the configured names.
+```yaml
+collections:
+  docs:
+    permalink: "/:collection/:path/"
+    output: true
+  tutorials:
+    permalink: "/:collection/:path/"
+    output: true

-## Specific visual customization
+## Custom schemes
 
-To customize your site’s aesthetic, open `_sass/custom/custom.scss` in your editor to see if there is a variable that you can override. Most styles like fonts, colors, spacing, etc. are derived from these variables. To override a specific variable, uncomment its line and change its value.
+### Define a custom scheme
 
-For example, to change the link color from the purple default to blue, open `_sass/custom/custom.css` and find the `$link-color` variable on line `50`. Uncomment it, and change its value to our `$blue-000` variable, or another shade of your choosing.
+You can add custom schemes.
+If you want to add a scheme named `foo` (can be any name) just add a file `_sass/color_schemes/foo.scss` (replace `foo` by your scheme name) 
+where you override theme variables to change colors, fonts, spacing, etc.
+
+Available variables are listed in the [_variables.scss](https://github.com/pmarsceill/just-the-docs/tree/master/_sass/support/_variables.scss) file.
+
+For example, to change the link color from the purple default to blue, include the following inside your scheme file:
 
 #### Example
 {: .no_toc }
 
 ```scss
-// ...
-//
-// $body-text-color: $grey-dk-100;
-// $body-heading-color: $grey-dk-300;
 $link-color: $blue-000;
-//
-// ...
 ```
 
 _Note:_ Editing the variables directly in `_sass/support/variables.scss` is not recommended and can cause other dependencies to fail.
+Please use scheme files.
 
----
+### Use a custom scheme
+
+To use the custom color scheme, only set the `color_scheme` parameter in your site's `_config.yml` file:
+```yaml
+color_scheme: foo
+```
+
+### Switchable custom scheme
+
+If you want to be able to change the scheme dynamically, for example via javascript, just add a file `assets/css/just-the-docs-foo.scss` (replace `foo` by your scheme name)
+with the following content:`
+
+{% raw %}
+    ---
+    ---
+    {% include css/just-the-docs.scss.liquid color_scheme="foo" %}
+{% endraw %}
+
+This allows you to switch the scheme via the following javascript.
+
+```js
+jtd.setTheme('foo');
+```
+
+## Override and completely custom styles
+
+For styles that aren't defined as variables, you may want to modify specific CSS classes.
+Additionally, you may want to add completely custom CSS specific to your content.
+To do this, put your styles in the file `_sass/custom/custom.scss`.
+This will allow for all overrides to be kept in a single file, and for any upstream changes to still be applied.
+
+For example, if you'd like to add your own styles for printing a page, you could add the following styles.
+
+#### Example
+{: .no_toc }
+
+```scss
+// Print-only styles.
+@media print {
+  .side-bar, .page-header { display: none; }
+  .main-content { max-width: auto; margin: 1em;}
+}
+```

+The parameter values can be numbers (integers, floats) and/or strings. When you omit `nav_order` parameters, they default to the titles of the pages, which are ordered alphabetically.

+Pages excluded from the main navigation can have parents and children. Navigation to and between excluded pages can be supported by the auto-generating list of child pages inserted at the bottom of each page, and by links to parents in the breadcrumbs at the top of each page.
+
+The following tests cover all combinations of excluded and included pages for the top level, child pages, and grandchild pages. The last binary digit in a page title indicates whether the page is included (1) or excluded (0); preceding digits refer to its parent and grandparent.

+This page does not have a `title`, and it is excluded from the navigation -- unless it is located in a Jekyll collection (which provides default titles). To exclude a title-less page from the navigation, regardless of whether it is located in a collection, set `nav_exclude: true`.
