Slider Text colour

Please could you tell me how I can change the colour of the header box on the slider?

Thank you very much

Hi @evadixon,

I hope you are well today and thank you for your question.

You can try changing this by adding the following CSS code in the Custom CSS option of the latest version of Sparkling theme on the below path.

Admin Area -> Appearance -> Customize -> Sparkling Options -> Other -> Custom CSS

.flex-caption h2.entry-title {
    background: rgba(68, 218, 90, 0.7);

Please change the color value in the above code to whatever you want to use by referring the following pages.

Best Regards,
