changing the size and the color of the button "view" – with demosite online

hello dear developer and fans of the great business-directory

i love this plugin

i run it on the page https://www.literaturen.org

and i am thinkin of the pro version – since this plugin is absolutly superb!

one thing i want to know: i want to change the size of the button “view”
see the results of the directory that i display on a widget – in the right side-block – called “leser, buchh?ndler”

how can i change the size (and if possible even the color)

love to hear from you
greetings
