Personalize portfolio

First, thanks for your help and great theme.
I am using perth-portfolio plugin in the front page

  1. I would like to include some space between projects.
    I have tried to include a white border in the featured image of the project and save .png but transparency is not working (I can not see the background)
    So, can I modify the perth-portfolio.php file to get what I want? I have no idea about coding.
  2. I hide the title of the project (hide title plugin), since I prefer include it in the project in order to modify the style: as an example with both titles.
    I can include the title in the featured image, but, what do I have to do to edit the .php so when I click on the image it goes to the external link page of the project? (if I remove the title the link dissapear).
    another option (the best one) is instead of that, remove the title when the project page is loaded; but I do not know how to do that (I only know the hide title plugin solution and it removes from the portfolio)


For the first question, I think you can use the css code below, but it will decrease the dimension of your image (put the code using custom css plugin):

.item.isotope-item {
    padding: 0 10px 10px;

h5.project-title {
    width: 93%;
    bottom: 10px;
    height: 95%;

And there also already a text field to put the external link for the project I think
