What have you tried so far?

I have tried styling the keyboard object. Code lines added below.

Code to reproduce

lv_obj_t * kb = lv_keyboard_create(lv_scr_act());

These are code lines that I used alternatively with the object. However, nothing happened.

    lv_obj_set_style_pad_row(kb, 10, LV_PART_ITEMS);
    lv_obj_set_style_pad_column(kb, 10, LV_PART_ITEMS);
    lv_obj_set_style_pad_row(kb, 10, 0);
    lv_obj_set_style_pad_column(kb, 10, 0);
    lv_obj_set_style_transform_height(kb, 10, LV_PART_ITEMS);
    lv_obj_set_style_transform_height(kb, 10, 0);
