Hello @ueffchen , sorry for the late reply! If you still got this problem, you can fix it in multiple ways: MMM Build in sizing You could change tableWrapper.className = "small mmm-vrr-table"; within MMM-Vrr.js on line 159 into tableWrapper.className = "medium mmm-vrr-table"; Specific font sizes for header add another line after MMM-Vrr.css:16 with you desired fontsize e.g: font-size: 50px; Specific font size within table content add this to the MMM-Vrr.css .mmm-vrr-table tr { font-size: 50px; }
