New file structure
The file structure of the program has been adjusted as follows:
- Contao back end
- upload folder (formally "tl_files")
- contains all generated RSS feeds
- system folder
- contains the customized templates
The "plugins" and "typolight" folders no longer exist in Contao 3.
Components of the CSS framework
The CSS framework has been overworked with regard to creating mobile websites and additional components have been added, which can be activated in the page layout. These include:
- CSS reset
- standardizes the different element formattings in the various browsers
- Layout builder
- creates a CSS layout based on the settings in the "page layout" module
- Responsive grid
- adds a responsive 12-column grid, which can be triggered with the CSS classes "grid1" to "grid12" and "offset1" to "offset12"
In this course, the layout builder switched to the "Holy Grail" layout, which displays the main column above the left and right columns. This can not only improve your search engine ranking, it also makes the two side columns slide below the main column on mobile devices.
Stronger focus on the module folders
Module folders are the central place to store own extension as well as system adjustments. Developers are to maintain as much resources as possible inside them, which has become a lot easier in Contao 3 thanks to the possibility to use arbitrary subfolders.
In addition, the autoload creator now supports unlimitedly nested structures to store PSR-0 compatible class libraries. To stress the focus on the module folders, the system/library folder has been entirely removed and the Contao framework has been moved into the system/modules/core/library folder. All external PHP libraries are now in system/vendor.
If you activate the "add the language to the URL" feature introduced in Contao 2.11, old URLs without the language fragment will now be redirected to a matching language instead of ending in a 404 error. This way you do not need to maintain a long list of .htaccess redirects.
The "image gallery" element and the "breadcrumb" module now use unordered lists (UL) to render the images or links. This change has to be adopted in customized templates as well as in the CSS code of the website.
Module loading order
In Contao 3, the core modules ("calendar", "comments", "core", "devtools", "faq", "listing", "news", "newsletter" and "repository") are loaded before the other modules. This change, however, does not solve the general problem of the alphabetic loading order, therefore further optimisation is planned.
