Wrapping Unbroken Strings

Question:

How can you ensure that a long string without any whitespace characters, like a DNA sequence, wraps correctly within an HTML textarea or XUL textbox?

Answer:

For block elements, like textarea and textbox, you can utilize the word-wrap CSS property to control how the text wraps. By setting it to break-word, it breaks the string at appropriate character boundaries, wrapping the text as needed.

Example Code:

<textarea>

This CSS style will wrap the long DNA sequence at the appropriate character boundaries, ensuring readability within the specified width of the textarea.
