CSSGrid

Description

The CSS Grid Layout Module offers a grid-based layout system, with rows and columns, making it easier to design web pages without having to use floats and positioning.

It is based on the Container control, so it works in much the same way. In fact, the Container can also do FlexBox positioning: it also has the special styling features. (As do Header, GridColumn and GridRow).

It can be used to create customized HTML element by setting the HTMLTag property to <div> or the name of almost any other HTML element. The content property is the innerHTML of the element. It can be empty, simple text or a complex HTML structure.

The FlexBox control can also be used as a wrapper for other controls you have set up in your project. Add them to the Design Screen as usual, then right click in a FlexBox and use Add Child. The control will then move into the FlexBox. If you reposition the FlexBox, the included controls ("children") will move with it. Use right click Remove Child to take a child out of a FlexBox.

The positioning of controls in a FlexBox defaults to 'relative'. When a control is added to a FlexBox, its left and top properties are set to 'initial', and 'Float:left;' is added to the Style property. The result is that children in a FlexBox act as Responsive Design elements: element flow and reflow is based on the screen size. If property is set to 'absolute', the top and left properties explicitly set the position of the children.

All the usual events are supported. FlexBoxes can contain other FlexBoxes.

To add a FlexBox control to your app, choose the FlexBox icon in the Toolbar, then position it on the Design Screen. Use the Property Editor to set the properties you need. Right click in the FlexBox to add children.

At runtime, controls can be added as children using the addChild() function: FlexBox1.addChild(Button1).
