Working with sliders – how to adjust the text style, box color and transparency

I’m working with the sliders. There are 2 specific things i need to do with them and i also have a few “curiosity” questions

The 2 specific things

1. I need to change the color or the box around the Title & Description text on the slider and
2. I need to change the % transparentcy of the same box.

I would like to make the box around this text color #13ed00 and i would like to make it a little less transparent.

other “curiosity” questions

You can change the color of the text on the slider but…

1. how do you change the style (font, characteristics (bold, underline, etc)) of the text
2. What if i wanted to move the box and the text to a different location on the slide? how could i do this?
3. What if i wanted to change the size of the box length or height that contains the text? How could i do this?
