I'm writing again because I took the liberty of reviewing the addon and I found that they have forgotten to add the width, height and line-height only in the public part because it exists in the live editor. Here the code, lines 681, 682, 683, 684.
$output .= $lodash->unit('font-size', '.sppb-icon .sppb-icon-container > i', 'data.icon_size', 'px');
$output .= $lodash->unit('width', '.sppb-icon .sppb-icon-container > i', 'data.icon_size', 'px');
$output .= $lodash->unit('height', '.sppb-icon .sppb-icon-container > i', 'data.icon_size', 'px');
$output .= $lodash->unit('line-height', '.sppb-icon .sppb-icon-container > i', 'data.icon_size', 'px');
I would like them to add it to the public part in the next version, here is the fixed code, line 345.
$iconSizeStyle = $cssHelper->generateStyle('.sppb-icon .sppb-icon-container > i', $settings, ['icon_size' => ['font-size','width','height','line-height']]);
