![删除顶部栏和块中的颜色](https://linux22.com/image/463015/%E5%88%A0%E9%99%A4%E9%A1%B6%E9%83%A8%E6%A0%8F%E5%92%8C%E5%9D%97%E4%B8%AD%E7%9A%84%E9%A2%9C%E8%89%B2.png)
我想只删除第一张幻灯片中的顶部水平深蓝色条,并在同一张第一张幻灯片的块中使用带有白色字母的深蓝色。代码如下:
\documentclass[10pt,xcolor={dvipsnames}]{beamer}
\mode<article> % only for the article version
{
\usepackage{fullpage}
\usepackage{hyperref}
}
\mode<presentation>
{
\setbeamertemplate{background canvas}[vertical shading][bottom=red!10,top=blue!10]
\usetheme{JuanLesPins}
\setbeamercovered{transparent}
\usefonttheme{serif}
}
\usepackage{pgf,pgfarrows,pgfnodes,pgfautomata,pgfheaps,pgfshade}
\usepackage[latin1]{inputenc}
\usepackage{colortbl}
\usepackage[english]{babel}
\setbeamercovered{dynamic}
\setbeamertemplate{items}[circle]
\setbeamertemplate{headline}
{%
\leavevmode%
\begin{beamercolorbox}[wd=\paperwidth,ht=3.1ex,dp=2ex]{section in head/foot}%
\hspace*{10.5pt}\usebeamerfont{section in head/foot}\insertsection
\end{beamercolorbox}%
}
\makeatletter
\newenvironment{noheadline}{
\setbeamertemplate{headline}{
{%
\leavevmode%
\begin{beamercolorbox}[wd=\paperwidth,ht=3.1ex,dp=2ex]{section in head/foot}%
\hspace*{10.5pt}\usebeamerfont{section in head/foot}
\end{beamercolorbox}%
}
}
\def\beamer@entrycode{\vspace*{-\headheight}}
}{}
\makeatother
\begin{document}
\begin{noheadline}
\begin{frame}
\begin{block}{}
\begin{minipage}[c][0.16\textheight][c]{\linewidth}
\centering \textbf{My slides}
\end{minipage}
\end{block}
\end{frame}
\end{noheadline}
\section{My slides}
\begin{frame}
My first slide
\end{frame}
\end{document}
欢迎任何帮助。谢谢!

在您的
noheadline
环境中,您明确地用深蓝色条替换了正常标题。如果您不想要此条,请不要进行此替换。要更改块的颜色,您可以使用
\setbeamercolor{block body}{bg=section in head/foot.bg,fg=white}
\documentclass[10pt,xcolor={dvipsnames,table}]{beamer}
\mode<article> % only for the article version
{
\usepackage{fullpage}
\usepackage{hyperref}
}
\mode<presentation>
{
\setbeamertemplate{background canvas}[vertical shading][bottom=red!10,top=blue!10]
\usetheme{JuanLesPins}
\setbeamercovered{transparent}
\usefonttheme{serif}
}
\usepackage[english]{babel}
\setbeamercovered{dynamic}
\setbeamertemplate{items}[circle]
\setbeamertemplate{headline}
{%
\leavevmode%
\begin{beamercolorbox}[wd=\paperwidth,ht=3.1ex,dp=2ex]{section in head/foot}%
\hspace*{10.5pt}\usebeamerfont{section in head/foot}\insertsection
\end{beamercolorbox}%
}
\makeatletter
\newenvironment{noheadline}{
\setbeamertemplate{headline}{\vskip\headheight}
}{}
\makeatother
\begin{document}
\begin{noheadline}
\begin{frame}
\setbeamercolor{block body}{bg=section in head/foot.bg,fg=white}
