I’m not sure, wether I haven’t found a thread with this question, or it really never has been asked before.
We want to use the Circumference header function whitch shows random header pictures after reloading a page. My problem is the high of the banner which is (without adding any text or other widget in the bannerarea) very small. Is there a way to make it higher, without adding a text or other visible stuff?
I know there is that nice tutorial for widgetkit, but I do not need a slideshow.
You can do custom CSS to change the height to your needs, but use a plugin for editing and creating CSS if you’re not using the child theme. Jetpack has Edit CSS built into it, otherwise a plugin you can check out is Simple Custom CSS.
