Perth portfolio transparency

Hi

I’m currently trying to make a website (not published online yet) but i have question, is there a chance to change transparency in portfolio plugin??

Did you mean the transparency of the blue title box? If so, could you please try to apply the following CSS code through the Simple Custom CSS plugin or child theme’s style.css?

.project-title {
  background-color: rgba(49, 91, 157, 0.6);
}

Then adjust the alpha value 0.6 to meet your need. It starts from 0 to 1. 1 will resulting solid color.

Regards,
Kharis
