CSS triangle with background image [duplicate]

Answer 1

Put the image as a background for a div, and just put negative values for the margin to make it overlay on the bar. Example (although estimated, in no way do I claim this to work) would be margin-left: -20px; margin-top: -20px; and have it after the line.

Alternatively go with @Py's answer, and you can use this CSS for the arrow, and do the same negative margins to make it line up.

#triangle-up { width: 0; height: 0; border-left: 50px solid transparent; border-right: 50px solid transparent; border-bottom: 100px solid red; margin-left: -20px; margin-top: -20px; }
