Thanks again - I can try to revise the website to minimize the overlap if there's no way to resize the slider. I am able to use the parameters to change the number and text labels - are there any other customizations that can be done to the on-line slider? I have a 0-100 scale and when I use those the labels, whenever I drag the bar, numbers show up above it on a yellow "tool tip" style label, but that scale is on a 1000 point scale which can be confusing to participants. Is there any way to make it so that the little label that pops up is consistent with the parameter anchor labels I specified?
