search on the main page

Try adding the GD Search widget to the sidebar.

Visit the WP Backend, go to Appearance – Widgets

Add the widget to the sidebar.

What you have added is WP search, that is a different thing.

Hi Volvo,

Thanks for your reply. You can use the custom CSS code below to achieve this. Insert into WP > Appearance > Customize > Additional CSS

input.search_text.gd_search_text {
    color: #000;
}

Hi Volvo,

Sorry for overlooking that one. Try this.

input.snear {color: #000;}
