Hello,

1. Paste the following code in your Custom CSS
(Appearance -> Theme Options -> Styling Options -> Custom CSS)

Code:

.flex-caption {
background: black;
}

In place of "black" you can put your color or color code.

2. Paste the following code in your Custom CSS
(Appearance -> Theme Options -> Styling Options -> Custom CSS)

Code:

.feature-content-inner .circle {
margin-bottom: 20px;
}

You can adjust the value of "margin-bottom" as per your requirement.

3. Paste the following code in your Custom CSS
(Appearance -> Theme Options -> Styling Options -> Custom CSS)

Code:

.feature-content-inner h2 a {
color: black;
}
.feature-content-inner p {
color: black;
}

In place of "black" you can put your color or color code.

4. Could you please specify the button with the help of screenshot images of which you want to change the color.
