Tips and tricks for authors

We use the Material theme for MkDocs. For a complete reference and inspiration please consult:

Material for MkDocs Reference

The following are a list of things we use commonly:

Admonitions

Tip

This is an admonition

See the list of supported types / icons and styles

Details

Details are the same as admonitions but expandable / collapsable. Use Just use ??? for initially collapsed and ???+ for initially opened details. Use the same image classes as with the admonitions

Info

Also available as collapsable items. Just use ??? instead of !!!

See the pymdown extension page to learn how this works in detail.


Links to other pages from the manual are written as relative links to the corresponding Markdown file. Make sure you reference the correct language! Just review other pages, you will find many examples.

[External link to frentix.com](https://www.frentix.com)

[Internal link to the group section](../../manual_user/groups/Using_Group_Tools.md)

In-Page references Just use

Add {: #anchor-example} to any title element to create an anchor that can be referenced by other pages or in an external link. Make sure you use the same anchor name for all languages of the same page.

[Link to the tables section in this page](#tables)

[Link to the courses section in a different page](../../manual_user/groups/Group_Administration.md#courses)

Downloads

Downloadable files such as PDF can be written as standard Markdown link. Some JS code will automatically add a target to open the file in a new window instead of replacing the current page. Supported types are pdf, odt, xlsx, docx.

If the download is represented with an image, the image tag can be embedded into the link tag. This is a bit cumbersome, but works well. See the example below

[![](assets/whitepaper-thumpnail.png){ class="thumbnail-xl border"}<br>whitepaper_learning_path_courses_en_final.pdf](assets/whitepaper_learning_path_courses_en_final.pdf)

Images

Image styles and css classes can be added to the image markup like this:

![Your image alt text](assets/smile.jpg){ width=100px align=right class="border shadow" }

Your image alt text

Important

The following notation to add special parameters to images is extremely sensitive to whitespace! Make sure 1. between the image markup und the left curly bracket is no space 2. after the left opening curly bracket and before the closing right curly bracket there is one space Otherwise the image styles will not be applied.

Sizes

There are some predefined image sizes that can be applied by assigning CSS classes. Use technique preferably over manually adding width or height:

CSS class Description Example
size16 shrink to match 16x16px 16x16
size24 shrink to match 24x24px 24x24
size32 shrink to match 32x32px 32x32
size48 shrink to match 48x48px 48x48
size64 shrink to match 64x64px 64x64
thumbnail-sm shrink to fit 150x100px thumbnail-sm
thumbnail shrink to fit 250x150px thumbnail
thumbnail-lg shrink to fit 300x200px thumbnail-lg
thumbnail-xl shrink to fit 400x300px thumbnail-xl

Aside images

Sometimes it is handy to have all images in the same width displayed at the right side. For this purpose we have the aside classes.

Aside classes behave respsonsive, meaning the images get smaller if there is not enough space on the screen

Info

Note that aside images must be placed before the content.

CSS class Description Example
aside-right-sm shrink to fit 150px width thumbnail-sm
aside-right shrink to fit 250px width thumbnail
aside-right-lg shrink to fit 300px width thumbnail-lg
aside-right-xl shrink to fit 400px width thumbnail-xl
![](assets/smile.jpg){ class=aside-right }

Tip

Aside images use CSS float layouts. All following paragraphs stay on the left side until the image is finished. Sometimes this is not what you want, e.g. because a new chapter starts. In such a case you need to manually clear the floating before the next chapter or paragraph or even image starts.

We have two options for this: 1) Use a horizontal ruler with *** or 2) use a custom markup <clear />

Styles

The following box styles are available

CSS class Description Example
shadow image with shadow shadow
border image with border border

Captions and figures

Images can be converted to figures with captions by adding an image title attribute with title="some caption here. See the example below:

![Your image alt text](assets/smile.jpg){ class=thumbnail-xl title="A great OpenOlat screenshot" }

Your image alt text

Info

Note that the alt text is an accessibility feature to describe the content of the image for users who can not see the picture while the title / caption is an additional text that conceptually explains or gives more insights about the meaning of the image.

Use the lightbox CSS class to enable the lightbox on an image. This makes the image clickable and enlargable. It is useful to use this in combination with the thumbnail styles:

![Your image alt text](assets/smile.jpg){ width=30px align=right class="thumbnail lightbox" }

Your image alt text

Specific width and other HTML attributes

Add { width=200px} for a custom size. This can also be combiend like this: { align=left width=200px }. Use custom width only if needed, if possible use the standard sizes using the predefined CSS classes.

Add { align=left } or { align=right } to format images left or right of text. Note that it is better to use the CSS classes from above as the CSS classes can have special rules for print and mobile devices while the align attribute will be applied in all conditions, even when it does not make sense at all.

Tables

Tables are cumbersome and error prone: - Tables need a header row and a separator in the second line - A row must be on one line, no line breaks allowed - cells can contain images, code block, foot notes etc, it is trial-and-error

See the manual for more info.

| CSS class | Description | Example |
| --------- | ----------- | ------- |
| `shadow` | image with shadow | ![shadow](assets/smile.jpg){ class="size64 shadow" } |
| `border` | image with border | ![border](assets/smile.jpg){ class="size64 border" } |
CSS class Description Example
shadow image with shadow shadow
border image with border border

As an example have a look at the table in the OpenOlat group section
