Edit comment I try many differents set-ups

Basic

• To post pieces of code, surround them with <code>...</code> tags. For PHP code, you can use <?php ... ?>, which will also color it based on syntax.
• Web page addresses and email addresses turn into links automatically, unless the parent tag has the 'nolink' class.
• Lines and paragraphs break automatically.
• Allowed HTML tags: <a> <em> <strong> <blockquote> <code> <ul> <ol> <li> <div> <p> <br> <pre> <h2> <h3> <h4> <h5> <figure> <img> <figcaption> <hr>
