Create a Blank Screen

There are templates for application home screens available when creating a screen, however, in this exercise we will build a screen from scratch to help us practice what we have learnt. 

1. Create a new screen from the Screen screen's home page.
   1. Name, Home.
   2. Description, Application home screen
   3. Template, Blank.
      1. Scroll to the right and select Blank.
   4. Click Create Screen
2. The screen will open.
3. Click in the middle to open the properties.
   1. Click the Styles tab.
   2. Scroll down to direction and set the following:
      1. Justify, Center
      2. Align, Center

   3. Insert excerpt
      _save _save nopanel true

       your changes.

Build Up the Centre Tile

1. Add a Tile
   1. From the Palette drag a Blank - Row tile onto the screen.
      1. Name, Centre.
      2. Click Confirm.
2. Open the properties for Centre.

      4. minHeght, 480px.

3. Insert excerpt
   _finish _finish nopanel true

    to save your changes.
   1. This invokes a screen update. If you do not see the changes you make on a screen, close and reopen the screen to force a refresh.
4. Add the centre areas.
   1. We will use simple areas to build up our screen structure:
   2. From the Palette in the basic layouts, click on Area - Column and holding shift, drag it onto the screen.
      1. Name, Left.
   3. Add a second Area - Column onto on the screen.
      1. Name, Right.

5. By default, the areas have a simple style applied so they can be seen easily.

   1. Click on the area Left.
   2. In the properties click the Styles tab.
      1. Tick Auto Size.
      2. Scroll down to the Position Settings section.
         1. Remove the Width and Height.
   3. Click the area Right and repeat the steps above.
   4. Both areas will now be the same size and we are ready to move on, see check point below.

Check Point

Your screen will look like the following:

Construct the Left Area

1. Click the area Left.
2. Add the following CSS Properties.
   1. margin, 20px
      1. This is short hand shorthand for placing 20px on all sides of the area. 
   2. minWidth, 320px.
   3. maxWidth, 350px.
   4. minHeight, 130px.
3. Click 

   Insert excerpt
   _finish _finish nopanel true

    to save your changes.
4. For While adding the following items from the palette to the screen use Shift+Drag:
   1. From the Headers section, add a Screen - Header to the Left area.
      1. Name, Title.
   2. From the Buttons - Additional section, add a Landing - Primary to the Left area.
      1. Name, Option 1.
   3. From the Buttons - Additional section, add a second Landing - Primary to the Left area.
      1. Name, Option 2.
   4. It may be necessary to move your new items into a different location or order, use the layers section to achieved achieve this and remember you only need to hold shift when moving an item into or out of an area.
