Arrows tutorial does not work for me

Hi,
I need to insert arrows in the slideshow and I have followed this tutorialbut it does not work for me.
I have changed “true” in main.js as described and added code in my css but nothing appears as you can see at www.giulianacovella.com
What can I do to check where is the error?
Thank you for help.

Hello,

The tutorial link in your post above doesn’t seem to be valid, can you please try to include it once again?

Kind Regards, Roman.

This is the link

Today I have verified that on Chrome and Internet Explorer I can see some dots on bottom of slider, on Safari I can’t see something.
However there are not arrows.

Hello,

It might be easier to use another slider, please check this documentation page:

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
