You can customize the appearance of the Component using CSS — the same way as for the regular HTML. All CSS styles of the Component provided by Flexmonster are in
flexmonster/flexmonster.css inside the package.
We recommend you writing your custom CSS in a separate file (i.e.
my-flexmonster-styles.css) and keep the original styles in
flexmonster.css without changes. This will help you update Flexmonster Component to the newest versions much quicker and safer. You will not break new features and will easily maintain your custom CSS.
