As for every other theme, Grain provides a simple way to adjust the page to your needs. You can modify any textual content, specify images and add links by updating the single /content/index.html file. For instance, it's easy to change section names for page navigation:
sections:-name:Our Services# a new section name
Or customize images and links, for example, for the clients section:
From the /content/index.html file, you can also modify modal windows of the projects located in the Portfolio section. In order to add the content of the modal window, you should specify the unique modal id in the project info and then refer to this id in the modal data:
portfolio:projects:-modal:portfolioModal1# project modal idimage:roundicons.pngmodals:-id:portfolioModal1# the same idtitle:Round Icons
Also note that the layout is automatically adjusted to newly created projects so you do not have to change the html.
To find out how to open, preview and deploy the theme please read the documentation.
