| <meta content="With clear: left, the top border edge of the last paragraph must be below the floating paragraph, i.e., 50px lower. That means that the margin-bottom of the first paragraph must not collapse with the margin-top of the last paragraph and clearance must be added such that clearance + margin-top of last paragraph = 50px, i.e., clearance = 50px - margin-top of last paragraph = 50px - 75px = - 25px." name="assert" /> |
