Is it possible to use any fraction symbol on a website, represented as ¼ rather than 1/4 for example?
From what I\'ve gathered, these are the only
The image below displays all unicode-defined fraction symbols. Each of them is treated as one single character. You can use all of them freely, of course, but if you want more, e.g. 123/321, then you should look out for a library that can create fractions dynamically.
An option for doing so would be using LaTeX. There is another question (with very good answers) on how to do this.
