我需要在标题和页脚的左侧和右侧之间留出一些空格``

\defbeamertemplate*{footline}{ru theme}{%
  \leavevmode%
  \hbox{%

      HTML color codes are the \textbf{hexadecimal triplets} representing the colors red, green, and blue.
  \vspace{0.25cm}

    These color codes can be used to change the color of the background, text, and tables on a web page.
