When referencing a third-party ui library, some styles are not selected or !important is added or the attribute style solution does not work:
use a separate <style></style>tag in the page , without scoped, write the style (style in the page) You can use multiple style tags), then you must have a custom tag, in the header, otherwise the style will easily pollute other pages.
Or you can use the deep selection styles such as'/deep/' and'>'.
