Card pattern title height - #5832

Done

• enforce equal height of title sections for cards on the same row

fly-by:

• remove active links from examples
• add more cards to examples to demo responsiveness
• remove description about responsiveness (this can be assumed for all patterns)

QA

• Open demo
• See that the cards for '4-Column Card with Image Top' have equal height p-content-card__body sections despite differing lengths of hover text.
• Using dev tools change the title length, description length - the body height should remain the same across both cards, based on the tallest content.
