LayerSlider – unwanted frame?

Dear Support,

I am havinf a hard time creating a slider that fits on the page the same way as it is shown on you demo page, see below:

See the frame stopping the slider from covering the whole width of the table?

Even the default demos have this frame. What is the configuration that you used in order not to have this frame?

Thank you
