1. Open your File Manager in your web hosting cPanel. (Not sure how to find the file manager? Here are instructions for Bluehost, Hostgator, and Godaddy). In your File Manager, follow this path: public_html > your_website_root > wp-content > themes > theme-name > functions.php. Sometimes the wp-content folder may be located right inside the public_html, in that case disregard the your_website_root portion of the path. Click “code editor” on the Functions.php file.
2. On the child_theme_name line (about five lines down), locate your theme name. It should be one word, like this:
3. Your theme name may be different from the one shown above, so keep it in your head or write it down. You’ll need it soon.
4. Click here and copy all of the code.
5. Scroll down and paste the code at the very bottom of the Functions.php file.
6. There are four places in the code you’ll need to change, and they have been marked with the word THEME. Replace the four instances of THEME with your theme name from steps 2/3. The theme name must be lowercase. Make sure to keep everything else in the code the exact same. When you are done, it should look something like this, but with your own theme name.
7. Save changes.
8. Go to WordPress > Appearance > Editor. Paste this code at the very bottom and then save.
9. To add the slider, go to WordPress > Plugins > Add New. We use and recommend Meta Slider. Search, install, and activate the plugin.
10. A “Meta Slider” tab will be added to your dashboard menu. Click there and create a new slider. You can set the dimensions of the slider and choose whether to display navigation buttons, arrows, etc.
11. To add the slider above your blog posts / below your header, go to WordPress > Appearance > Widgets. Drag the Meta Slider widget into your “Below Header” widget area and choose the slider you created in step 10. Save. Congrats, you now have a slider below your header!
You can also add a slider on its own homepage. To do this, add the Meta Slider widget to the “Home Top” widget area. Make sure that your site is set to display a home page instead of your posts at WordPress > Settings > Reading.
