How can I change the font and background image for buttons?
I’m pretty sure this needs to be done using a css snippet but I can’t figure out what selectors to use. Please give me some guidance and also tell me how I could have found this information on my own (I looked in the Theme Filter Reference, Theme Developer Docs, and the Advanced Modules Reference).
Hey Doug,
Unfortunately, you can’t do both via BB settings. The button inherits the font-style from the theme. And you can’t set a background image, just a color. You can always override it via custom CSS though. You can place an additional class to the button you want the styling to apply to, then target it like so…
.fl-builder-content .class a.fl-button {
background: red;
}
This is custom CSS, which isn’t specific to BB. If you want to, you can learn it on the link below.
