Say you have a really nice splash page, but you want to hide your navigation on that page so users are directed to a specific page of your site first after visiting it. If you're familiar with CSS you can do this easily, and thanks to how CSS works you can do this without customizing your theme itself.
In this example, I've used Saucy as the theme for a site selling oranges. I chose the Splash page layout for the page, and now I really only want the front page to be the site name, slogan, and a button that sends people to a special deals page first.
This looks great, but I'd really like to hide the navigation so that the first page visitors go to has current special deals. The first step is to publish the site. Modern browsers like Chrome and Safari come with an extremely handy tool called the Web Inspector. There are many powerful things you can do with this, though in this example we only need to get the class or ID of the element containing the navigation. Right-click or CTRL-click on your navigation, then choose "Inspect".
A window will pop up, and the element you right-clicked on will be selected within the code displayed. Mouse over parent elements until you get the element that contains all of your site navigation. Web Inspector makes this really handy because it will highlight the element on the page. You can see in my screenshot that the element I want to hide has an ID of "header-wrap".
Great! We're now two thirds of the way done. Next, go back to the editor and go to the Pages tab. Select your home page, then click on "Advanced". In the Header Code field, enter this code:
<style>
#header-wrap { display:none; }
</style>
After you've done that, re-publish your site and check it out!
Congrats! You've hidden the navigation on a single page of your site, and you're still using a standard theme. What if you're using a different theme and this hides your logo? Go back to web inspector, and look into child elements until you find the element that only contains your navigation. Are you using one of our themes that has a hamburger icon all the time? The same principle applies- use Web Inspector to find the element that has just the icon, and use that ID or class with the same CSS rule above.
As you can see, each theme is different so what you're going to be hiding will vary from one theme to another, however the basic concept is the same. Remember, you should be comfortable working with CSS as we don't provide assistance with custom CSS and HTML changes. If you have any trouble, just delete the code from the Header Code field and start over.
Yes, some changes are only applied on the live site.
