Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Bootstrap 4 Dark theme

Bootstrap 4 dark theme that supports togging dark/light themes as well. There is no fluff, it changes the color of Bootstrap and that's it, no new thing to learn or unlearn, just Bootstrap, but Dark!

Versioning

SemVer is used to keep things easy for everyone.

How to use

Official builds are available in the public npm registry.

npm install @forevolve/bootstrap-dark --save

The package contains the content of the dist directory which includes the Bootstrap JavaScript files, for convenience, and the Bootstrap Dark CSS files. To load the dark theme, <link> the bootstrap-dark.css or the bootstrap-dark.min.css instead of the bootstrap[.min].css file. You can load the bundled JavaScript files, the original ones or the file from the CDN of your choosing.

Example:

<link rel="stylesheet" href="/css/bootstrap-dark.min.css" />

CDN

You can also load the files using jsdelivr by following this pattern: https://cdn.jsdelivr.net/npm/@forevolve/bootstrap-dark@{NPM PACKAGE VERSION}/dist/{PATH TO THE FILE}.

Here is the preceding example using jsdelivr:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@forevolve/[email protected]/dist/css/bootstrap-dark.min.css" />

Dark/Light toggle

You can <link> both the toggle-bootstrap.css and the toggle-bootstrap-dark.css files to allow toggling the normal/dark theme based on your page body.

  • To display the original Bootstrap color, apply the bootstrap class on your body, like <body class="bootstrap">.
  • To display the Bootstrap Dark theme, apply the bootstrap-dark class on your body, like <body class="bootstrap-dark">.

If you want to support print, load the toggle-bootstrap-print.css or toggle-bootstrap-print.min.css file after the others.

Example:

<link rel="stylesheet" href="/css/toggle-bootstrap.min.css" />
<link rel="stylesheet" href="/css/toggle-bootstrap-dark.min.css" />
<link rel="stylesheet" href="/css/toggle-bootstrap-print.min.css" />

Using jsdelivr CDN:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@forevolve/[email protected]/dist/css/toggle-bootstrap.min.css" />
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@forevolve/[email protected]/dist/css/toggle-bootstrap-dark.min.css" />
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@forevolve/[email protected]/dist/css/toggle-bootstrap-print.min.css" />

Check out the samples app for more info about this feature.

Themeable .navbar

When using the toggle-* stylesheets, you can create .navbar that uses the current theme. Light when <body class="bootstrap"> and dark when <body class="bootstrap-dark">.

Example, instead of navbar-light bg-light or navbar-dark bg-dark, use .navbar-themed, like this:

<nav class="navbar navbar-expand-lg navbar-themed">...</nav>

Check out the samples app for more info about this feature.

prefers-color-scheme

From version 1.1, I added two new css files: bootstrap-prefers-dark.css and bootstrap-prefers-light.css. Those two files use prefers-color-scheme media query instead of relying on a body's css class. There is also a new bootstrap-light.css file that is bootstrap, plus the .navbar-themed light addon.

There is two possible combination:

  • default (no prefers-color-scheme specified or prefers-color-scheme: light): default bootstrap (light), prefers-color-scheme: dark: bootstrap dark
  • default (no prefers-color-scheme specified or prefers-color-scheme: dark): bootstrap dark, prefers-color-scheme: light: default bootstrap (light)

Here is an example for a light default:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@forevolve/[email protected]/dist/css/bootstrap-light.min.css" />
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@forevolve/[email protected]/dist/css/bootstrap-prefers-dark.min.css" />

See ./samples/html/prefers-dark-default-light.html for a working example.

Note that the print css is included in bootstrap-light.min.css.

Here is an example for a dark default:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@forevolve/[email protected]/dist/css/bootstrap-dark.min.css" />
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@forevolve/[email protected]/dist/css/bootstrap-prefers-light.min.css" />

See ./samples/html/prefers-light-default-dark.html for a working example.

Note that the print css is included in bootstrap-dark.min.css.

bootstrap-${default}-prefers-${specific}.css

Added in version 1.2 (preview) and 2.0, the stylesheets bootstrap-dark-prefers-light.css and bootstrap-light-prefers-dark.css leverage the prefers-color-scheme CSS media query and allow a default color scheme followed by a preferred color scheme.

Technically, they are a combination of two CSS. Their high-level structure looks like the following:

/*
DEFAULT STYLES (including print styles):
bootstrap-light.css or bootstrap-dark.css
*/
@media (prefers-color-scheme: light|dark) {
    /*
    SPECIFIC COLOR STYLES:
    bootstrap-prefers-light-color-only.css or bootstrap-prefers-dark-color-only.css
    */
}

You can use these by loading one of them like this (ex.: default: light with dark support):

<link rel="stylesheet" href="/dist/css/bootstrap-light-prefers-dark.min.css" />

You can also use jsdelivr CDN.

<!-- Bootstrap Dark by default with `prefers: light` support -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@forevolve/[email protected]/dist/css/bootstrap-dark-prefers-light.min.css" />
<!-- OR -->
<!-- Bootstrap (Light) by default with `prefers: dark` support -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@forevolve/[email protected]/dist/css/bootstrap-light-prefers-dark.min.css" />

How to build

If you want to build the theme manually, modify it or even contribute, this section explains how.

Prerequisites

  1. You need npm to build this project; see Node JS for more info.
  2. You need .NET Core 3.1+; see .NET Core Downloads for more info.

    You can also test using the HTML sample, but there are more pages in the .NET app.

Getting started

  1. Clone this repo
  2. Run npm install
  3. Go to the samples/razor-pages directory (cd samples/razor-pages)
  4. Run dotnet restore

Starting the project

  1. Run dotnet run (from the samples/razor-pages directory) or if you are using VS Code, Start Debugging will work.
  2. Run npm run watch in a second terminal

Once you started both server and the watch command, the browser-sync proxy should open in a browser at the following URI: http://localhost:3000.

Other build info

There is a few npm and gulp scripts.

npm scripts

  1. gulp-watch simply runs gulp watch
  2. browser-sync-proxy starts browsersync watching for any wwwroot/css/*.css changes
  3. watch run both previous scripts in parallel

gulp scripts

  1. build-theme compile the theme to css.
  2. copy-dist-to-razor-pages copy the content of the dist folder to samples/razor-pages/wwwroot (used by the Razor Pages).
  3. copy-dist-to-html copy the content of the dist folder to samples/html (used by the HTML sample).
  4. copy-dist-to-samples executes copy-dist-to-html and copy-dist-to-razor-pages in parallel.
  5. copy-bootstrap-js copy the bootstrap js files to the dist/js directory.
  6. watch execute copy-bootstrap-js then watch to rebuild the theme.
  7. default runs copy-bootstrap-js and build-theme then copy-dist-to-samples.

The project structure

  • samples is the samples folders.
  • samples/html is a plain HTML samples app.
  • samples/razor-pages is the ASP.NET Core application that is used to test the theme. This directory is not packaged.
    • Pages are the ASP.NET Core Razor Pages. That's the preview.

      Why .NET Core? Well, I wanted to script some loops, and I know .Net; so I picked Razor Pages to do just that: dynamic pages! Moreover, it is open source and cross-platform.

      If you think that something else would be better, feel free to open an issue about it; I would not mind switching to another technology (see the Contribute section below).

    • Services are the web pages services; so far it's pretty thin.
    • wwwroot are the web assets; the dist files are copied there.
  • assets are the project assets (like the screenshot in the readme file).
  • dist are the distributable files; if you want to copy/paste the files into your projects, that's the ones. They also include bootstrap JavaScript files, unaltered.
  • scss are the source theme files.
  • Other files (root): npm, license, readme, etc.

Contribute

To contribute, start by opening an issue or reply on an existing issue so we can discuss your feature or bug to find the best way to approach it.

Once we settled on a strategy, you can then Fork/Code/Open a PR.

  • Please add yourself in the package.json contributors array.
  • Please keep PR focused on a single feature, it is easier for everyone this way and it helps keep the conversation focused. I way prefer multiple smaller PR than a single huge one.

Thanks in advance for your contribution.

See Contributing to ForEvolve open source projects and Contributor Covenant Code of Conduct for more information.

Release notes

Since CI build numbers are automated, it is hard to know in advance what the next deployed build number will be, so the (latest) version represents that version.

4.0.0

  • Fix pre and code color, setting the $pre-color variable to $gray-100, overriding the default of $gray-900 for the dark theme.

No breaking changes expected. This version only change the code/pre color. The major bump is to override the pre-release package that I deprecated recently during the no abandonned PR #63. I was not able to delete the package on NPM, so this should fix the issue.

3.0.0

  • Fix an issue where dark colors were not taken into account because of the missing variable maps $colors and $theme-colors. This might be a breaking change.
  • Update $yiq-text-dark from $gray-900 to $gray-800 and $yiq-text-light from $gray-400 to $gray-200 so the text looks better with the updated color maps.

2.1.1

  • Bump Bootstrap to 4.6.2 (from 4.6.0)

2.1.0

  • Add a Themed page in the sample app.
  • Add the following themed utilities that flip from dark to light depending on the theme:
    • .bg-themed (dark: .bg-dark | Light: .bg-light)
    • .text-themed (dark: .text-light | Light: .text-dark)
    • .alert-themed (dark: .alert-dark | Light: .alert-light)
  • Add the following themed utilities (inverted colors) that flip from dark to light depending on the theme:
    • .bg-themed-inverted (dark: .bg-light | Light: .bg-dark)
    • .text-themed-inverted (dark: .text-dark | Light: .text-light)
    • .alert-themed-inverted (dark: .alert-light | Light: .alert-dark)

2.0.0

  • Add bootstrap-dark-prefers-light.css which default to Bootstrap dark and display the light colors if the user's prefers-color-scheme: light.
  • Add bootstrap-light-prefers-dark.css which default to Bootstrap and display the dark colors if the user's prefers-color-scheme: dark.
  • Add bootstrap-prefers-dark-color-only.css which is only the colors of bootstrap-prefers-dark.css. This is autogenerated by clean_non_color_attr.js.
  • Add bootstrap-prefers-light-color-only.css which is only the colors of bootstrap-prefers-light.css. This is autogenerated by clean_non_color_attr.js.
  • Add clean_non_color_attr.js gulp plugin (based on gulp-css-remove-attributes).
  • Update .NET/Razor Pages sample to use these new CSS files.

The preview versions 1.2.x was ¾ of this. We bumped the version due to the $card-color change (see below).

Breaking changes

The $card-color variable has been reverted from $gray-200 (#e9ecef) to null (default Bootstrap value) due to a color issue in the dark/light theme.

1.1.0

  • Update bootstrap-dark.css to include the .navbar-themed class (dark version).
  • Add bootstrap-light.css which is bootstrap plus the .navbar-themed class (light version).
  • Add bootstrap-prefers-dark.[css|scss] that is the equivalent of bootstrap-dark.[css|scss], without the print, wrapped in a @media (prefers-color-scheme: dark) media query.
  • Add bootstrap-prefers-light.[css|scss] that is the equivalent of bootstrap-light.[css|scss], without the print, wrapped in a @media (prefers-color-scheme: light) media query.
  • Add two samples to show this usage: ./samples/html/prefers-dark-default-light.html and ./samples/html/prefers-light-default-dark.html
  • Update .NET/Razor Pages sample to use these new CSS files.

1.0.0

  • Update to Bootstrap 4.6.0
  • Move the Razor Pages app to the samples/razor-pages directory
  • Add a new plain HTML app in the samples/html directory
  • Move the CI/CD pipeline from Azure DevOps to GitHub Actions
  • Migrate versioning from manual PowerShell scripts to use Nerdbank.GitVersioning
  • Update README

1.0.0-alpha.1091

  • Fix form validation feedback to address issue #40
  • Add another form sample

1.0.0-alpha.1089

  • Add table examples
  • Fix form validation without .was-validated #40

1.0.0-alpha.1087

  • Update Bootstrap to 4.5.0
  • Update dependencies to fix vulnerabilities
  • Fix form validation #40

1.0.0-alpha.1075

  • Remove p a text-decoration: underline;
    • This was conflicting with .btn in p.
    • Moreover, Bootstrap does not implement such a thing so bootstrap-dark should not either.

1.0.0-alpha.978

Darken the following elements:

  • Dropdown
  • Select
  • Breadcrumb
  • Pagination

1.0.0-alpha.974

  • Update Bootstrap to 4.4.1
  • Update other dependencies

1.0.0-alpha.937

  • Darken Toasts

1.0.0-alpha.902

  • Update <hr /> color

1.0.0-alpha.899

  • Utilities (borders)
    • Update the default $border-color to $dark
  • Tables
    • Enforce that $table-border-color is based on the new $border-color
    • Enforce that $table-color is based on $body-color
    • Enforce that $table-hover-color is based on $table-color
  • Jumbotron
    • The $jumbotron-bg color is now used

1.0.0-alpha.888

  • Add a themeable .navbar component, using the css class .navbar-themed, that:
    • When body.bootstrap, the navbar becomes .bg-light and .navbar-light.
    • When body.bootstrap-dark, the navbar becomes .bg-dark and .navbar-dark.

1.0.0-alpha.863

  • Move the print import out of the dark/light body class. This should fix bugs like .navbar being display: none by default when loading the .min.css stylesheet.

  • A new file is introduced: toggle-bootstrap-print[.min].css. This stylesheet applies the print styles from bootstrap and has been extracted so it is included only once (not once with the toggle-bootstrap.css and once with the toggle-bootstrap-dark.css). If you don't support print, you can omit this file; if you do, include it last. For example:

    <link rel="stylesheet" href="/css/toggle-bootstrap.min.css" />
<link rel="stylesheet" href="/css/toggle-bootstrap-dark.min.css" />
<link rel="stylesheet" href="/css/toggle-bootstrap-print.min.css" />

1.0.0-alpha.845

  • Update the project description, the "How to use" section, and add the "Release notes" section

1.0.0-alpha.842

  • Add support for dark/light toggling

1.0.0-alpha.774 & 1.0.0-alpha.723

  • Initial dark theme

More darkness!

The following project applies bootstrap-dark to the bootstrap documentation site allowing deeper testing of the theme:

Special thanks

I started this project based on the Bootstrap Theme Kit by Alexander Rechsteiner at Hacker Themes. This allows me to publish a lighter version of the theme; making it easier to be used (compared to the full Bootstrap Jekyll docs).

Bootstrap 5

If you are looking for a Bootstrap 5 alternative, I suggest you look at vinorodrigues/bootstrap-dark-5. @vinorodrigues did a great job already, and whenever I have time to help, I'll do that there. I believe that we better focus on building one solid project than maintaining many. As for Boostrap 4, nothing changes about this project.
