Description

The material available online about Web Design to integrate into the applications developed with GeneXus is astonishing! There is a boom of the so-called "CSS Frameworks," which complement JavaScript development Frameworks (for example, JQuery). Applications can be made more attractive thanks to CSS Frameworks.

These CSS Frameworks provide hundreds of widgets, compositions, sources, etc.
Some of the most popular ones are as follows:

  • Bulma.io
  • Bootstrap
  • SemanticUI
  • Pure.css
  • Kube
  • Materialize

What is a Base Library

A Base Library is an external resource that uses a CSS Framework. For example, Semantic UI, Bootstrap, etc.

Base Libraries are external CSS & JS & Assets files that are globally installed with GeneXus.

How to create a new Base Library inside a KB

First, to create a Base Library, compress all the required files (CSS, JS, etc.) into a ZIP file and save it with .gxlibrary extension.

Next, you can include that Base Library in your Knowledge Base by creating a new File object and specifying the path to upload your Base Library.

Finally, the Library will be offered for this property so that you can select it.

While several libraries can be included in the KB, using the same Base CSS for different objects is recommended to maintain consistency.

Notes:

1) To just add external references to resources, create a references file inside the library; each line of this file will be considered a reference.

For example, you could add a glue.references with the following content:

ace.js
ace.css

This means GeneXus will add references to those files when some Theme or User Control uses your Base Library.

2) If you create a User Control object and set its Base CSS property = None, it won't look appealing. 

Runtime/Design time

This property applies only at design time.
