@HiNooril you can change the format of the text by adding this to your style.css file –
.slide-excerpt-border p {
font-size: 18px;
}
This should override the plugin’s css. You can add font-family and then the font that you want to use, and you can change the size of the text, etc with the above code. If it doesn’t show up at first try adding !important at the end like this –
.slide-excerpt-border p {
font-size: 18px !important;
}
