AB.showRunHeader(); // Show run header (in case does not show automatically) AB.hideRunHeader(); // Hide run header (still exists) // The run header div floats on top of the canvas. // Sometimes this interferes with other page elements and need to: AB.removeRunHeader(); // Remove run header entirely AB.headerCSS ( css ); // Give run header some css AB.headerLHS(); // Put run header on LHS AB.headerRHS(); // Put run header on RHS AB.headerWidth ( w ); // Give run header a fixed width // Useful if writing info every step into (variable width) header. // Can lead to header 'flicker' as it keeps changing width. // Solution: Give it fixed width.
