Wrapping Long Words in a Div: A Cross-Browser Guide

While Internet Explorer offers a word-wrap style, individuals may seek a cross-platform solution for word-wrapping long strings within a div. This article explores both CSS and JavaScript methods to achieve this objective.

CSS Method:

CSS provides several properties that can enable word-wrapping. The following snippet should work in most browsers:

.wordwrap {
  white-space: pre-wrap;      /* CSS3 */
  white-space: -moz-pre-wrap; /* Firefox */
  white-space: -pre-wrap;     /* Opera <7 */
  white-space: -o-pre-wrap;   /* Opera 7 */
  word-wrap: break-word;      /* IE */
}

By applying the wordwrap class to the div containing the text, browsers will automatically wrap long words to fit the available width.

JavaScript Method:

If CSS is not an option, JavaScript can also be used to simulate word-wrapping. One approach involves wrapping each character individually in a span element:

function wrapWords(div) {
  var text = div.innerHTML;
  var wrappedText = "";
  for (var i = 0; i < text.length; i++) {
    wrappedText += "<span>" + text[i] + "</span>";
  }
  div.innerHTML = wrappedText;
}

This function iterates over characters, creating a span for each character, and then inserts the wrapped text back into the div.
