This is called the Portfolio Section in the theme.
Use it to display your best visual content.
To edit it, go to:
dashboard – appearance – customize – widgets – home main content area – AT Portfolio Section
Click on the upside-down triangle and you’ll see the screen below:
You can change the Title and Short Description to whatever you want.
Next, you’ll need to create sub pages for the parent page following this tutorial.
The parent page can contain general information about all your portfolio items.
The sub pages will contain more detailed information about each portfolio item, in this case recipes. Please note that each sub page needs to have a featured image, as this is what will be displayed on the front end of your site. The recommended size for the image is 700 x 500 pixels.
Portfolio Number determines how many images will be displayed
Number of Words in Content determines how long your description in the sub pages will be.
Column Number determines how many columns you want your pictures to be displayed in, side by side.
You can use the Button Text and Button Link URL to connect to your portfolio parent page, which will add a button to the section, or leave it blank if you prefer and it won’t have a button below that section.
Click the blue save & publish button to save your changes.
