苦于ppt格式修改的繁琐，最近在用beamer写ppt，还在熟悉的过程当中，遇到一个block的样式问题，查了一些资料，顺便做点总结
\documentclass
{beamer
}
\begin
{document
}
\begin
{frame
}{Mathematics
}
\begin
{block
}{Mathematics
}
The
function \
(\phi \colon \mathbb
{R
} \to \mathbb
{R
}\
) given by \
(\phi
(x
) = 2x\
) is continuous at the point \
(x
= \alpha\
),
because
if \
(\epsilon
> 0\
) and \
(x \in \mathbb
{R
}\
) is such that \
(\lvert x - \alpha \rvert
< \delta
= \frac
{\epsilon
}{2
}\
),
then
\begin
{equation*
}
\lvert \phi
(x
) - \phi
(\alpha
)\rvert
= 2\lvert x - \alpha \rvert
< 2\delta
= \epsilon.
\end
{equation*
}
\end
{block
}
\end
{frame
}
\end
{document
}
由于没什么主题，显示出来非常朴素
在\documentclass{beamer}后面加入下面这段代码，对block的标题和主体部分的前景和背景颜色做一些修改
\definecolor
{uibred
} {HTML
}{db3f3d
}
\definecolor
{uibblue
} {HTML
}{4ea0b7
}
\definecolor
{uibgreen
}{HTML
}{789a5b
}
\definecolor
{uibgray
} {HTML
}{d0cac2
}
\definecolor
{uiblink
} {HTML
}{00769E
}
\setbeamercolor
{block body
} {bg
= uibgray
}
\setbeamercolor
{block title
}{fg
= white,bg
= uibred
}
另外，删除代码equation后的*号，会自动添加公式的编号，Latex确实灵活强大
