How to use this sample
Summary
This example uses the conditional operator ? to apply a class (sp-field-severity--warning) to the parent <div /> element when the value in the current field is less than or equal to 70. This causes the field to be highlighted when the value is less than or equal to 70, and appear normally if it's greater than 70.
