There is no easy fix for the caption other than incorporating the caption as part of the image within the carousel. Again, this is something you can do in an image editing application. Essentially, create an image with some bottom white space and add the text into the bottom area and then save the image. If you want search engines and screen readers to read your caption, simply type your caption into the Alt field in the Appearance section of the properties panel. You can set Alt text for every slide. Your images should look something like this:
The arrows can be placed outside of the carousel by using the class manager. Open the class manager window from the window menu. it will look like this:
Click on the plus symbol highlighted in the above image.
This will open a window where you can add a class. Click on the Subclass Lib box and scroll down the list to “Carousels”. From the sub-options select “Carousel Prev Arrows”. Next, repeat the process and select “Carousel Next Arrows” This is how it looks:
This will add the two classes to the list of classes. Starting with one of the arrows, click the settings icon highlighted in red in the illustration below.
This will open the class editor where you can change various attributes of the arrows. To move their positions select the metrics tab and click on the right or left margin as highlighted below:
Select the right margin when editing the next arrow class and the left margin when editing the previous arrow class. In both cases set the margin to a minus number. In my example, I’ve set the margin to -100. This will move the arrows outside of the carousel. You can increase the number further if you want more space between the arrow and the carousel.
Note: Your changes will be applied to all carousels you may add to your project.
