Avoid breaking line between two words when resizing [duplicate]

Answer 1

You use a nonbreaking space. The HTML entity for it is  . You'll probably want a non-breaking hyphen (‑) in T-2 as well:

Ask for it it when contracting until 2016/09/30 with T‑2 Rate

Example:

var target = document.getElementById("target");
var originalWidth = target.innerWidth || target.clientWidth;
var width = originalWidth;
tick();
function tick() {
  width = width < 10 ? originalWidth : (width - 10);
  target.style.width = width + "px";
  setTimeout(tick, 400);
}

#target {
  display: inline-block;
  border: 1px solid #ffffd;
}

<div id="target">Ask for it it when contracting until 2016/09/30 with T&#8209;2&nbsp;Rate</div>

Answer 2

Just use <span style="white-space: nowrap"> for nonbreaking parts, as MDN states.
