Custom styling of Elevio’s elements comes with multiple restrictions:First, you should check you can’t achieve what you want with display settings.Second, we don’t test each release against your custom styling so Elevio could break on your site at any time. We also don't guarantee any styling but our own and so are unable to provide support on any custom stylings that are not compatible.Third, there are only some documented CSS selectors (see below). The undocumented CSS selectors appear in the DOM as something like: ._1gtFd. You are, of course, free to use them but be aware that they can change at any time and we make no guarantees about their availability.Fourth, any custom styling will not apply to articles since they are displayed in an iframe. To style articles see the embeddable_css_file option in setSettings.With that said, you can use the following CSS selectors to style certain elements:#_elev_ioThis ID is on the root of every Elevio element..elevioResetThis class is on the root of every Elevio element. It’s used to set base styling (e.g. font, etc). See the generated styling for all the options.._elevio_widgetOn root of the Assistant.._elevio_launcherOn root of the launcher.._elevio_popupOn root of all popups.._elevio_tooltipOn root of all buttons (AKA tooltips).._elevio_tooltip_1234On root of all buttons, where 1234 is the actionId (the associated article or module ID).._elevio_nothingOn root of buttons that have display type nothing.._elevio_underlineOn root of buttons that have display type underline.._elevio_qmarkOn root of buttons that have display type qmark.._elevio_pulseOn root of buttons that have display type throbber.._elevio_module_iconOn root of all the module items in the menu.._elevio_module_icon_1234On root of all the module items in the menu, where 1234 is the ID of the module.._elevio_searchOn root of search component
