Step 13: Margins and Paddings

Our app content is still glued to the corners of the letterbox. To fine-tune our layout, we can add margins and paddings to the controls that we added in the previous step.

Instead of manually adding CSS to the controls, we will use the standard classes provided by OpenUI5. These classes take care of consistent sizing steps, left-to-right support, and responsiveness.

Coding

webapp/view/App.view.xml

To layout the panel, we add the CSS class sapUiResponsiveMargin that will add some space around the panel. We have to set the width of the panel to auto since the margin would otherwise be added to the default width of 100% and exceed the page size.

If you decrease the screen size, then you can actually see that the margin also decreases. As the name suggests, the margin is responsive and adapts to the screen size of the device. Tablets will get a smaller margin and phones in portrait mode will not get a margin to save space on these small screens.

Margins can be added to all kinds of controls and are available in many different options. We can even add space between the button and the input field by adding class sapUiSmallMarginEnd to the button.

To format the output text individually, we remove the description from the input field and add a new Text control with the same value. Here we also use a small margin to align it with the other content. Similarly, we could add the standard padding classes to layout the inner parts of container controls such as our panel, but as it already brings a padding by default, this is not needed here.

<mvc:View

				<Page title="{i18n>homePageTitle}">

							<content>
								<Button

									press=".onShowHello"
									class="sapUiSmallMarginEnd"/>
								<Input
									value="{/recipient/name}"
									valueLiveUpdate="true"

								<Text
									text="Hello {/recipient/name}"
									class="sapUiSmallMargin"/>	
							</content>
						</Panel>

Conventions

  • Use the standard OpenUI5 CSS classes for the layout if possible.
