How to change section anchor in Zerif
It's really easy to change the section anchor in Zerif, and all other themes:
Okay, so I'll give you an example of how we could change the ID of Portfolio. First you need to create a child theme: http://docs.themeisle.com/article/14-how-to-create-a-child-theme
In case you don't have a sections folder created in your child theme, you can create it and copy the section you want to change the anchor from your parent theme sections into the child theme sections folder.
After that, in the section you want example: /sections/portfolio.php file, change `id="works"` to `id="portfolio"` and that's all. Now the anchor for the Portfolio will be portfolio instead of works.
Hope this helps. :)
