Resizing Font to Fit a Div on a Single Line Using JavaScript

Situation:

You have an article with a title in an

tag, but you want to ensure that the title remains on a single line regardless of its length.

CSS Solution:

There are no CSS attributes that allow you to automatically resize text based on the div width.

JavaScript/jQuery Solution:

1. Create a hidden div with the following styles:

   position: absolute;
   visibility: hidden;
   white-space: nowrap;
   font-family: [same as the title's]

2. Copy the title text into the hidden div.
3. Set an initial font size for the hidden div.
4. Implement a while loop that increments the font size of the hidden div until its width matches the width of the parent div.
5. Set the calculated font size to the original title.

Optimization:

To improve performance, you can optimize the while loop to decrease iterations:

1. Set a starting font size.
2. Get the width of the test div.
3. Calculate the width factor between the original div and the test div.
4. Adjust the font size based on this factor, rather than incrementing/decrementing by one unit.
5. Test the width of the test div.
