Hi,
if we understand you well, you think on single portfolio.
For remove “Project details” please open your single-portfolio.php file
(you can find it here \wp-content\themes\revelance\single-portfolio.php)
and when you edit that file on line 53 you have this code:
<h3><?php _e('Project Details', 'ABdev_revelance') ?></h3>
Delete that code or comment it and “Project details” should be remove. If you want to delete all after “Project details” (and that would be CLIENT, DATE, IN, SKILLS, LINK) you should delete or comment all from the line 53 to line 92.
If you want to change title icon go to folder css
(you can find it here \wp-content\themes\revelance\css)
and inside that folder you have core-icons folder and entypo folder. In core-icons folder you have demo.html file (open that in your browser) and inside you can find all core icons. Inside entypo folder you can also select what icon you want. Just be sure to take exactly the right code below icon (for example e606) and after that open you style.css and on the line 259 you have:
.main_title:after{
display: block;
content: "";
height: 36px;
width: 36px;
position: absolute;
bottom: 25px;
left: 50%;
margin-left: -18px;
color: #e42382;
font-family: 'entypo';
font-size: 18px;
content: "\e637";
}
Change content: "\e637";
to icon code you like.
To remove featured image on line 48 you have
the_post_thumbnail('full', array('class' => 'portfolio_item_image'));
Delete or comment that line.
I hope this help you :)
Cheers
