Main menu → Create → Skins

If you see the menu item Skins under Main menu → Create, you can create skins yourself, edit them, and use other people’s skins on your portfolio pages and your profile page.

Bemerkung

If you do not see the menu item Skins, please check with the site administrator. There are two possibilities why you may not be able to use skins:

  1. Skins have not been enabled for the site. A server administrator will need to enable skins for the site.
  2. If skins are enabled for the site in general, your Mahara institution may not allow the use of skins. Your institution administrator can change that in the institution settings.

4.3.4. What is the difference between themes and page skins?

Themes

  • Have been present in Mahara in their current form since 1.2.

  • Must be uploaded directly onto the web server by a system administrator.

  • Can override the page template for every single screen in Mahara, giving total control over how everything is displayed.

  • Depending on site and institution settings, there may be:

    • a single theme for the whole site
    • a theme for every institution
    • the possibility for users to choose their own theme for browsing the site
    • the possibility for users to apply a particular theme to each portfolio page, the page themes

Skins

  • Can be created, shared, exported and uploaded by users via Main menu → Create → Skins.
  • Are less powerful than themes. They can only change page colours, fonts and background images, and add extra CSS. Basically they add one additional user-controlled CSS stylesheet to a page.
  • Can only be applied to user-created portfolio pages. They don’t change the way any other part of Mahara is displayed.

When skins and themes collide

  • If users apply a skin to one of their pages, it adds one additional CSS stylesheet to the page. This is in addition to the CSS from the theme.
  • Naturally, any particular skin might not look good in all themes, especially if the theme has changed the underlying page templates for portfolio pages.
  • If you’re a theme designer, the good news is that the skin stylesheet is itself a page template (skin/style.tpl). So, you can specify which page elements each of the skin settings should apply to by overriding that page template.

4.3.5. Disallow skins on a theme

If you use Mahara at an institution, you may wish to prevent anyone making changes to your institution theme with a skin so that your corporate design is preserved and that portfolios created for assessment purposes or as showcases of work done at your institution for example are easily recognizable as belonging to your institution. However, at the same time, you do want to give portfolio authors in your institution the freedom to create personal portfolios with other themes and apply skins to them.

Themes are allowed to use skins per default. If you want to change that, you need to add the parameter $theme->skins = false; to the file themeconfig.php in your theme folder. Once done, users of this theme will see the following message:

‚Your Mahara site theme „Name of the theme“ does not support page skins. This means the skin you select will have no effect on how you see this page, but it may affect the page’s appearance for other users viewing the site with a different theme.‘

Warning that skin cannot be applied

Warning that skin cannot be applied

Bemerkung

This option works best when users cannot choose the theme in which they want to browse the site. If they do, and choose a different theme from the institution theme, then they could see the skin applied to the page because then the underlying theme is their personal one which may allow skins.
