When padding is set for the component, the space of the scrollbar is squeezed inward. 8e41f4b71Sopenharmony_ci 9e41f4b71Sopenharmony_ciSince API version 10, the scrollbar margin in the **\<List>** component fixed at 4 vp, not affected by padding. 10e41f4b71Sopenharmony_ci 11e41f4b71Sopenharmony_ci## cl.arkui.2 Change of Space Reserved for Scrollbar Top and Bottom 12e41f4b71Sopenharmony_ci 13e41f4b71Sopenharmony_ci**Change Impact** 14e41f4b71Sopenharmony_ci 15e41f4b71Sopenharmony_ciBefore change, the space reserved for the top and bottom of a vertical scrollbar (or left and right of a horizontal scrollbar) is fixed, as a result of which the scrollbar may be cut by the rounded corners of the scrollable container component. 16e41f4b71Sopenharmony_ci 17e41f4b71Sopenharmony_ciAfter change, the space reserved for the top and bottom of a vertical scrollbar (or left and right of a horizontal scrollbar) is dynamically calculated based on the rounded corner radius of the scrollable container component. For example, when the rounded corner radius of a **\<Scroll>** component is 0, the space reserved for the top and bottom of its vertical scrollbar is 0, which means that the scrollbar can scroll to the bottom of the **\<Scroll>** component. 18
