Select the container to apply the styles. Text element supports adding nested text elements for applying CSS styles. One example is to create a rounded box by adding images to the corners of the nested text elements. The container of a text element without any nested elements is called "outer". The next nested element is "inner-1" and the next element within this one is called "inner-2" etc. Please note that a nested text element without any styles assigned to it will not be generated.
