I'll break down the parts of the code: [ ](#" style="border: none; border-top: 0.25em solid transparent; border-bottom: 0.25em solid transparent; border-left: 14em solid #7e2d40; line-height: 1.25em; font-size: 1.05em; display: block) The main part is the hidden anchor tag (an html link, typically for a website): [ ]() Whatever is inside the [ ] is the displayed code, so I just added a blank space there. Whatever is inside the ( ) is what is linked. The way Roll20 parses this, is it changes things to create proper HTML code. What Oosh figured out is that you can 'break' the html link by using a fake call of '#"' and add style information, which is what comes afterwards. At that point it's just understanding HTML/CSS style code. The important thing for you to know here is each attribute is separated by a semicolon ';', and the very end of the line needs a closing parenthesis ')'. You can look up specific style tags to see if there are other options you'd like to use, but here's the breakdown of what is in the code I used: border-top: 0.25em solid transparent; --> This makes the top part of the line transparent border-bottom: 0.25em solid transparent; --> This makes the bottom part of the line transparent border-left: 14em solid #7e2d40; --> This makes the left part of the line solid red and 14 units wide line-height: 1.25em; --> This sets the height of the line font-size: 1.05em; --> This sets the height of the font display: block; --> This 'blocks' the display to start on a new line and use the whole width Bonus question 1 answer: You could either simply add a blank line before the red line in your code to add more space, or you can add 'margin-top' and 'margin-bottom' attributes to increase the space above and below the line. margin-top: 0.25em; margin-bottom: 0.25em; Bonus question 2 answer: You can change the color of the line by changing the color in the 'border-left' attribute: '#7e2d40' is the red currently used for the line and title. You just need to find the hex reference for the color you want and use that. The color in the macro is the same color that gets used by the 'npc_action' template, so I'm not sure what color you want to change it to. Bonus help: If you are using Google Chrome as your browser, you can right-click on the chat bar on whatever element you are curious about and click on 'inspect'. (I think Firefox has a similar functionality.) At the bottom of the sidebar that shows up on the right, you'll see all the CSS that is currently being displayed, which is how I figured out that the red arrow is just a line, not a graphical image. The attributes that have a line strikethrough mean that they are being superceded by some other CSS, so look for the ones that don't have a strikethrough.
