<link rel="author" title="Andreu Botella" href="mailto:abotella@igalia.com">
<link rel="help" href="https://drafts.csswg.org/css-overflow-4/#block-ellipsis">
<link rel="match" href="reference/block-ellipsis-032-ref.html">
<meta name="assert" content="If the block-ellipsis soft wrap opportunity is preceded by hangable whitespace, it is removed before placing the ellipsis.">
<style>
.clamp {
  line-clamp: 1;
  border: 1px solid black;
  font-family: monospace;
  margin-bottom: 1em;
  /* The non-hanging text in the first line is 22 to 26ch, plus 1ch for the ellipsis. The hanging whitespace is extra 8ch */
  width: 29ch;
}
.right {
    text-align: right;
}
.justified {
    text-align: justify;
}
.green {
    color: green;
    font-weight: bold;
}
.hangs {
    white-space: pre-wrap;
    background-color: red;
}
</style>

<p>Test passes if the text in the following blocks, including the ellipsis, is aligned to the proper
margin, and if they all have some green text and no red.</p>

    This text is <span class="green">left-aligned</span><span class="hangs">        </span>Clamped
