This project contains the source files for the Gray BRCA Pre-Cancer Atlas website. The site is built using Jekyll, and is structured such that it can be rendered directly in GitHub to display within their GitHub Pages site hosting service.
The site (as currently stands) is comprised of 6 Collections:
- pages - These provide the content for the top-level pages of the website. Pages are gathered within the collection for organizational purposes, so that the source files are not left 'loose' at the root of the site.
- data-cards - These entries provide the source content for the items in the Data section of the website, as well as the Data module on the homepage.
- publications - These provide the content for the Publications section of the website. At a minimum, entries should contain front matter that can be used to populate the publication list on the Publications landing page. They can also contain body content, which can then be displayed as a standalone summary page for the publication.
- projects - These entries provide the source content for the items in the Projects section of the website. No standalone pages are build for these items, but body content is displayed within the Projects landing page.
- people - These entries provide the source content for the items in the People section of the website. No standalone pages are build for these items, but body content is displayed within the People landing page list.
- graphics - These entries are used whenever a graphic with captioning needs to be displayed. Each item in the graphics collection has a title assigned, an image, and then body copy which can be marked up as needed, and will then be rendered out within a
<figure>
/<figcaption>
HTML structure.
The site makes use of the imgix image processing service. This means that in most cases, the author can upload non-sized images, and the sizing will be managed automatically for them. The exception to this is if an image is specified directly in the body content of a page, without the use of a graphic entry. In those cases, care should be taken to ensure the image is optimized for web delivery.
Note that the imgix service can also be used for images specified in the body of an entry by using the site.imgbaseurl
property as a prefix for the file path. This allows for using the imgix API on the image, which includes the ability to scale and crop. For example:
![]({{ site.imgbaseurl }}general/image.jpg?w=500)
More information on the imgix API can be found here.
The site currently makes use of four data files (contained in the _data directory), which can be edited as needed as the site grows over time:
- menus.yml - This contains the structure for the main site navigation. Note the use of the section_id value. This is used to trigger menu highlighting for sub-pages within a given section. Also note the use of the children attribute, which is used to specify submenus for a given top-level section. If a top-level menu item is not actually a link, but rather just a container label, simply provide an empty string for the url value. For example, in this demonstration hierarchy, the 'About' section is simply a top-level label/container for the 'Atlases' and 'People' pages below it:
main: - name: "About" section_id: about url: "" target: "" children: - name: "Atlases" url: "/atlases" target: "_self" - name: "People" section_id: people url: "/people" target: "_self" - name: "Publications" section_id: publications url: "/publications" target: "_self" ...
- people.yml - The people entries are organized on the People landing page according to group. The groups are specified in the people.yml file, and the key value is assigned to the entries in the people collection to form their group associations.
- publications.yml - The publications entries are grouped by their associated groups on the Publications landing page. The groups are specified in the publications.yml file, and the key value is assigned to the entries in the publications collection to form their group associations.
- announcements.yml - The 'Publications' module on the homepage is managed via this file. There is 1 array: publications_software, the entries of which are represented by 'cards' within the module. Follow the structure provided within the file for additional entries, for example:
publications_software: - title: "The spatial landscape of progression and immunoediting in primary melanoma at single cell resolution" description: author: "Nirmal, et al." year: 2022 publication: "Cancer Discovery" image: "publications/the-spatial-landscape-of-progression-and-immunoediting-in-primary-melanoma-at-single-cell-resolution_v2.png" link: "https://doi.org/10.1158/2159-8290.CD-21-1357" label: Publication # [Publication|Software|Method] target: "_blank" # [_self|_blank] link2: # Optional - will be displayed below primary link label2: # [Publication|Software|Method] target2: # [_self|_blank] ...

Collection data is generally displayed within corresponding sections of the site (eg. the publications collection is displayed on the Publications page). Collection entries can also be pulled into other pages of the site using some available include specifications:
-
Graphics - Any entry in the graphics collection can be embedded in a page using the following syntax:
{% include graphic.html content='my-graphic-entry' %}
This will display the graphic -- with its associated title and caption information -- inline in the page on mobile, and will 'float' the content to the right on desktop displays.
-
Publications - A list of any of the entries in the publications collection can be embedded in a page by providing either a comma-delineated string of publication filenames, or an array of publication objects. For example:
List of filenames:
{% assign publicationList = 'my-publication-filename,my-other-publication-filename' %} {% include pub-list.html list=publicationList %}
Or, array of publications:
{% assign publicationArray = site.publications %} {% include pub-list.html publications=publicationArray %}
-
Data Cards - A list of any of the entries in the data-cards collection can be embedded in a page by providing either a comma-delineated string of publication filenames, a tag to filter on, or an array of data-card objects. For example:
List of filenames:
{% assign cardList = 'my-data-card-filename,my-other-data-card-filename' %} {% include cards.html list=cardList %}
Or, tag to filter on:
{% include cards.html tag='my-tag' %}
Or, array of data-cards:
{% assign dataCardArray = site.data-cards %} {% include cards.html cards=dataCardArray %}
For any pages that render out body content (eg. publication pages), a few notes:
-
Image Alignment - Images used in the body of our pages can be aligned left or right, and shown at 50% width on desktop, by using the
float-half-left
andfloat-half-right
classes on the images. For example:![](/images/general/image.jpg){: .float-half-right }
-
Enlarge Image - This gives the ability to 'float' an image to the left or right on desktop displays, with a 'Click to enlarge' CTA that opens the image at a larger size inside of a modal overlay. Usage:
{% include enlarge-image.html src='general/my-image.jpg' float='right' alt='' %}
-
Expand/Collapse - Expand/collapse functionality can be added to blocks of content by making use of the
<details>
and<summary>
HTML elements. Note that a custom value can be assigned to the expanded state of the summary button via adata-collapse-label
attribute:<details> <summary data-collapse-label="I'm done">Expand</summary> ... </details>
By default (if no value is provided), the label on the expanded button will be 'Collapse'.
-
Table Layouts - Standard Markdown table formatting is supported, and tables will be automatically styled. There is also an alternate table layout available, where each table record is specified and rendered out in its own block, with the label values displayed down the first column, with values of the record directly to the right (column 2). This is useful in tables with many columns, that would otherwise require horizontal scrolling. To use the alternate format, specify a pipe-delineated string of labels, and then a separate pipe-delineated string of values for a single row/record. The left-column-head-table.html include is then used to render out the block:
{% assign labels = "Heading 1 | Heading 2 | Heading 3" %} {% capture values %} Value 1 | Value 2 | Value 3 {% endcapture %} {% include left-column-head-table.html labels=labels values=values %}
NOTE: capture is used here to specify the values content, because it allows for syntax highlighting in the editor. assign can be used as well, but will not provide highlighting.
-

Video Card - The video card layout essentially wraps either the vimeo or youtube embed files (described above) in a card wrapper, with the title and description (optional) displayed below it, with a Click to enlarge link that opens the video in a modal overlay. Note that all parameters available on the respective vimeo and youtube includes are also available on the video card includes. In additional, 2 other parameters are available:
Parameter Description title
The title of the video description
Video description Vimeo Card
{% include vimeo-card.html id="158396727" title="My Video Title" description="A short description of this video." %}
YouTube Card
{% include youtube-card.html id="8gWMytghieg" title="My Video Title" description="A short description of this video." %}
Note that video cards are typically displayed within a grid context, with 2 cards per row on desktop displays. The markup for this (using bootstrap's grid) is as follows:
<div class="row mb-4"> <div class="col-md-6 mb-4"> {% include vimeo-card.html id="679370096" title="My Video Title" %} </div> <div class="col-md-6 mb-4"> {% include youtube-card.html id="8gWMytghieg" title="My Other Video Title" description="This video has a description." %} </div> </div>

To make updates to the site, you simply need to push git updates to the GitHub repository on the main branch. You may also run a local version of the site for review purposes by cloning the git repo, and installing Jekyll (per the specifications in the Gemfile). This can be done by running the following in the root project directory:
bundle install
Once the required files are installed, you can spin up the dev server via:
bundle exec jekyll serve
The site will then be available at localhost:4000
If you would like to make updates to the javascript bundle, you will also need to install the packages specified in the package.json file. This can be done via:
npm install
...or, if using Yarn:
yarn install
Once installation is complete, you can start up the development workflow like so:
npm run dev
...or, if using Yarn:
yarn dev
The development workflow includes a webpack setup for packaging the javascript files in src/js and placing them into the assets/js directory for use by the jekyll site. Updates will be re-bundled automatically while the dev script is running.
When ready to generate a production build, ensure that the dev script has been stopped (CTRL+C) and then run the build script:
npm run build
...or, if using Yarn:
yarn build
bundle exec jekyll serve
), there is no need to re-build the javascript before pushing files to GitHub. All other site build processes (page rendering, Sass processing, etc) is handled by the GitHub Pages rendering system. Note that as of the initial site build, GitHub Pages uses Ruby version 2.7.4, and Jekyll 3.9.3.
