# Custom CSS Options Panel

To add custom CSS to the deck, start with the selector you would like to override. For example, if you wanted to remove the caption area on the Tool Kit lens completely, you could write this selector:

.lens-tool-kit.sd2-title-dark .sd-node-title-box,\
.lens-tool-kit.sd2-title-light .sd-node-title-box {\
display: none;\
}
