Every time you write a tutorial and want to show any type of coding language you run into issues. Basically, the browser wants to run the language as code, whether HTML, Javascript, CSS or PHP. The problem is that you don’t. By escaping the characters and turning them into the HTML code equivalents, you can show code live on websites.
Doing this by hand is incredibly tedious which is why there are tons of converters available on the web. I have grown accustomed to the Quick Escape tool housed over at Accessify which does the job. Until I create my own tool one day, this works perfectly.
