I haven't posted it in this forum, but it's the same CSS as what's on GitHub for Legacy sanitization. Everything I've read on these forums says even when the character sheet moves away from the legacy sanitization the roll templates must still follow those rules.  Here's a snippet of the CSS, though...  CSS:     .  sheet-rolltemplate-roll   div ,   .  sheet-rolltemplate-roll   span ,   .  sheet-rolltemplate-roll   h1 ,   .  sheet-rolltemplate-roll   h2 ,   .  sheet-rolltemplate-damage   div ,   .  sheet-rolltemplate-damage   span ,   .  sheet-rolltemplate-damage   h1 ,   .  sheet-rolltemplate-damage   h2 ,   .  sheet-rolltemplate-gritty   div   {       box-sizing :   border-box  ;    }     .  sheet-rolltemplate-roll   span  .  sheet-templateCondition   {       font-size :   0.5  em  ;    }     .  sheet-rolltemplate-roll ,   .  sheet-rolltemplate-damage   {       background :   url  (  "  <a href="https://raw.githubusercontent.com/finderski/SWT/master/BackgroundImages/graph_paper_web.jpg" rel="nofollow">https://raw.githubusercontent.com/finderski/SWT/master/BackgroundImages/graph_paper_web.jpg</a>  "  );    }     .  sheet-rolltemplate-roll   .  sheet-templateMain ,   .  sheet-rolltemplate-damage   .  sheet-templateMain ,   .  sheet-rolltemplate-info   .  sheet-templateMain   {       display :   -webkit-box  ;       display :   -ms-flexbox  ;       display :   flex  ;        -ms-flex-pack  :   distribute  ;       justify-content :   space-around  ;        -ms-flex-wrap  :   wrap  ;       flex-wrap :   wrap  ;       width :   100  %  ;       padding :   0  px  ;    }     .  sheet-rolltemplate-roll   .  sheet-templateMain ,   .  sheet-rolltemplate-damage   .  sheet-templateMain   {       background :   url  (  "  <a

 .  sheet-rolltemplate-damage   .  sheet-templateHeader   {       width :   100  %  ;       margin :   0   0   15  px   0  ;       padding :   20  px   0   0   0  ;    }     .  sheet-rolltemplate-roll   .  sheet-templateBody ,   .  sheet-rolltemplate-damage   .  sheet-templateBody   {       width :   100  %  ;       margin :   0  ;       padding :   0  ;       display :   flex  ;    }     And the
