bs init to create a new presentation along with a
template directory in the current directory. The
template directory is needed for
backslide to transform your Markdown files into HTML presentations.
Then edit the file
presentation.md to get started.
You can create as many markdown presentations as you want in the directory, they will all be based on the same template.
If you want to start a new presentation using your own custom template, you can use
bs init --template <your_template_dir>.
You can also set the environment variable
BACKSLIDE_TEMPLATE_DIR to change the default template used by
bs serve to start a development server with live reload.
A page will automatically open in your web browser showing all your presentations.
Select one to see the preview, you can then edit your
.md file and see the changes immediately as you save the file. Any style change will also be applied live.
Just edit the
template/style.scss file and make changes according to your needs.
The base theme already provides some helpful additions.
The stylesheet is written in Sass, but you can use plain CSS instead if you feel like it, as long as you don't change the file extension.
bs export to export all your
.md files as HTML presentations.
Everything will be inlined in the HTML document (scripts, css, etc) so you don't need a network to show your presentation. If you have images, it's best to include them as data-uri in your markdown, but local images links are inlined too during export.
If you have set a
title variable in your document (like this
title: My Awesome Presentation), it will be used as the HTML document title, otherwise the file name will be used.
Note: you can strip presenter notes from the exported HTML using the
--strip-notesoption, and remove slide fragments with the
bs export --web <file>.md to export a presentation into a static HTML website.
Files within the
template folder and from the
img folders will be copied to the destination folder.
bs pdf to export your all
.md files as PDF presentations.
Note: you can remove slide fragements with the
This feature is based on Decktape.
