If you would like to enable your website for languages that read right-to-left, instead of left-to-right, you can select this in Settings.
In the portfolio builder, click Site Settings, then scroll down to find the Text Direction setting.
Click the dropdown and select right-to-left (RTL). If you want to switch back to left-to-right at any point, you can do it here.
To learn more about RTL, see this article.
