Why Did I Want a Change?
I made the decision to use a slider for my home page banner, instead of the static image supplied by the theme. The theme had branding text as a layer over the static image. With the change to a slider the branding (logo) that was part of the original theme options is gone. The theme actually comes with a built-in slider, but that slider.that slider didn’t have all the functionality I wanted So, I used a different plugin with the features I wanted. But, now, I need to compensate for the lost branding.
Your logo is an important part of the branding on your site. The theme provides for a small site title and tagline in the row above the slider, but the name is very small (see asterisk). That would make sense if I were going to use the business name in large text on the slider images, but I’m not. So, I need to rethink the size of the branding information in the top row!
It’s easy enough to make it larger with a simple CSS change. I already have a Kahuna child theme started for an earlier change.
How Did I Change the Font Size?
Since WordPress added the Customizer function in 2015, themes have been adding new areas of the posts and pages that can be formatted through the Customizer. So, the first step is to check whether changing the formatting of the site-title can be done in the customizer. Note that this post assumes you are not using a builder theme, such as Divi, Avada, etc.
An aside: Changing formatting in the Customizer puts that code in the database, instead of in your style sheet. For that reason, I often do those changes in code to keep my stylesheet the authority source for formatting.
