First: Adds "px" on background color css property.

Result: https://www.joomshaper.com/forum/question/22861

Reason: Missing element "'content_background' => false" on line: "$css .= $cssHelper->generateStyle(".sp-slider {$uniqid} {$inner_uniqid}", $inner_value, $contentStyleProps, ['btn_box_shadow' => false,'content_color' => false, "content_text_shadow" => false, 'content_margin' => false]);"

Second: Missing animation styles. $animation_settings variable is always empty because of this line: "if ($content_tabs == 'content_animation')"
