Decrease the space between the sections, change font, change background color

Hi @Bably,

Please find the answer to your questions below.

1. Decrease the space between two sections?
A: Please go to Appearance >> Customize >> Additional CSS and add following CSS

#home-page-widget-area .widget {
    padding: 80px 0;
}

In above code 80px padding (space) is added between two section. You can reduce it as per your requirement.

2. Change the font in the overall website?
A: Free version of this theme do not have the option to change fonts. You need to use upgraded premium version for it.

3. Change the background Color only when I am using the Text widget in the home page.
A: You can use following CSS to change background of text widget section

#home-page-widget-area section.widget_text {
    background: #ededed;
}

Please change color as per your requirement in above code.

Thank you.
