Once you have provisioned
your Power Apps portal, you can use the themes and
portal to customize them. Power Apps portals, the enable basic theme
feature is set to off. When you turn on this feature, you can use default
themes called presets. You can also create copies of the preset themes for
additional customization. Let's revisit the
portal created earlier and examine how themes could
improve its appearance. Select ''Apps'' from the
left navigation pane, then select your portal
app and click ''Edit''. Select ''Themes'' from
the left navigation pane, and then turn on the
enable basic theme toggle, if it's not already turned on. Select any default theme
from the available presets. The selected theme is then
applied to your portal. To see how this would
look to a customer, click ''Browse website'' in the top right corner
of the command bar, you'll notice the website
opens in a new tab. To return to the
Power Apps Studio to make further changes, simply switch back to the tab you were
working in previously. If the choices offered in the presets gallery are not suitable for the look
you're trying to achieve, or if they do not suit
your company branding, then it is possible
to create a theme. To do this in the
portals, Edit window, select ''Themes'' again from the navigation menu on the left, and then click ''New theme''. The new theme will be visible in the custom section
of the themes pane. You can update the theme
name, description, color, and other settings
in the details pane that opens on the right-hand
side of the screen. A description can be useful in situations where there are different versions
of the same theme. Any color can be adjusted by entering the
appropriate code. To see what the customized
settings will look like, you can click on the Browse
website button again to have the webpage open in another
tab with the changes applied. Finally, once you are happy with the look of the website,
click ''Save''. Using themes is a
simple as that, I'm sure you'll be customizing
your portals in no time.
