-The controls in the Bootstrap carousel are images that have a white background. To use a different symbol or to make them more visible in light backgrounds you can use custom CSS.  Here is an example:
-
-```css
-.carousel-control-prev-icon,
-.carousel-control-next-icon {
-  height: 100px;
-  width: 100px;
-  background-image: none;
-}
-
-.carousel-control-next-icon:after {
-  content: '\003e';
-  font-size: 55px;
-  color: yellow;
-}
-
-.carousel-control-prev-icon:after {
-  content: '\003c';
-  font-size: 55px;
-  color: yellow;
-}
