Why is there a line at bottom of login form ?

[chmike]

In the login form layout example, there is a horizontal line at the bottom below the login button. Why is it there ? How could I remove it ?

Do you mean this line ?

If so, this line is a part of visual styling of ui stacked segment.

If you want remove stacked styling, just remove stacked class.
Then ui segment will look like below:

Thank you. Where can I find the meaning or effect of the different classes ? What is the effect of the 'teal' class name for instance ?

The documentation should cover this. For example all variation of segments are here: https://fomantic-ui.com/elements/segment.html
teal is a color modifier.

Sorry, I missed that documentation on stacked segments. It was clearly documented. Is there documentation of the color models ? I couldn’t find it. What other colors do I have as alternative to teal ?

[ColinFrick]

The different colors are in the documentation (f.e. for buttons https://fomantic-ui.com/elements/button.html#colored). You can also find all different colors in the colors.less file
