# The part of post disappears after “<” mark without space

I include the bug here in this post (visible in edit)

• I agree this looks like a bug, but in which situtation do we have < that should not be in code or math environments? Since there is a colorful and helpful box, I don't think newcomers should be too confused. – Raphael Jul 4 '16 at 8:52
• When posting bug reports, it's usually best to include a screenshot so the post can be made sense of later. – Raphael Jul 4 '16 at 8:58
• @Raphael I disagree with "support" tag, this is a bug, maybe not that important, but still, what next? – Evil Jul 4 '16 at 13:12
• @Oded changed tags which means he as dev on SO's payroll does not think this is a bug. Little to be done. FWIW, since this is documented behaviour I'd agree it's not a bug. If you want it changed, it's a feature request. – Raphael Jul 4 '16 at 13:37

< is also the starting character of any HTML tag - which a subset of is allowed in markdown.
As such - it isn't escaped by the parser - and your browser thinks that everthing after < (until a > is reached) is a tag. So isn't shown on the page.
