Static HTML elements are written directly in SAPUI5

HTMLWeb DevelopmentFront End Technology

SAPUI5 allows the developer to use their own static HTML elements with the use of UI5 controls in certain areas. It is not closed framework and allows you to use a sap.ui.core.HTML control to write any amount of plain HTML within an area rendered by UI5 so it allows you to easily mix HTML and UI5 controls.

HTML created by UI5 controls, however, is created dynamically, but that's how many JavaScript UI libraries work when providing higher-level UI elements that would be hard to write in static HTML.

You can refer to below link of SAPUI5 which tells more about HTML SAPUI5 development:
