@techfinderr: Go to Dashboard=> Appearance=> Customize=> Theme Options=> Custom CSS box and add the following CSS:
@media screen and (min-width: 481px) {
#homepage-message .left-section {
text-align: center;
width: 80%;
}
}
By changing color, do you mean to change the background color of Promotion Headline Bar? If yes, add the following CSS:
#homepage-message {
background-color: #00cc99;
border-bottom: 1px solid #00cc99;
border-top: 1px solid #00cc99;
}
Note: You have an error in you Custom CSS. You are missing a closing curly brace at the end. Put an ending curly brace and then only add the above CSS or it won’t work properly.
