The paragraph not showing inside the container

Hi,

I turn the container background color to black but it only show black, but not show my words in the

Anyone have suggestion?

This is the viewport, it is all black, no word inside the container.

Of course there are words in the container. Try to select the text and you will see them.

The problem is that the text is black (default text color) on a black background. font is the property to select the font. Use color to set the color.
