– Change the color of the button in the slider and in the header?
– Change the font size of the text in the slider?
– Get rid of the entry content on the homepage, but not in the slider?
Go to Appearance >> Customize >> colors >> Here you can select color for header and use color scheme for the button.
To remove the content in the homepage go to the pages you have select as a static front page and remove title and content.
Hello, as an update I was able to figure out the content piece. But the buttons (neither one) will change color. I am pretty positive I have the CSS correct.
