大家好。这是我在这里的第一个问题！我正在制作一张海报。我试图将主标题的颜色改为：背景——海蓝色，文字颜色——白色。我成功地直接使用 \textbf{\color{white}{main title}} 将主标题的文字颜色改为白色，但不知何故找不到改变背景颜色的方法。我尝试更改所有颜色选项以查看是否有任何效果，但没有成功。有人能帮我吗？非常感谢！ baposter.cls

欢迎使用 TeX.SE。海报标题的背景设置没有快捷键。设置过程如下：
headerheight用定义headerheight=0.10\textheight。这意味着海报页面高度的 10% 将用于写入海报标题。- 设置键
background=user。这意味着您将定义如何使用宏创建海报baposter背景\background{}。 - 编写代码来绘制和/或填充背景。在本例中，您希望标题使用不同的颜色。我们可以通过以下方式实现此目的：
\fill [fill=HeaderBackground] (current page.north west) rectangle ([yshift=-\headerheight] current page.north east);其中定义您选择的颜色，我们绘制一个等于海报宽度且高度等于（如上所定义）的HeaderBackground矩形。headerheight
绘制背景的完整代码是：
\background{
\begin{tikzpicture}[remember picture,overlay]%
%the poster background color (the whole page)
\fill[fill=PosterBackground] (current page.north west) rectangle
(current page.south east);
%the header (just the top of the page where the title is written)
\fill [fill=HeaderBackground] (current page.north west) rectangle
([yshift=-\headerheight] current page.north east);
\end{tikzpicture}
}
这样做会产生以下结果：
其他一些评论。\headerbox是一个已弃用并被 替换的宏\begin{posterbox} ... \end{posterbox}。 不同之处在于您不能在\headerbox宏中包含逐字内容，而因为\begin{posterbox} ... \end{posterbox}是一个环境，所以您可以包含逐字材料。 如果您喜欢可以使用 创建的网格布局baposter，那么您可能会对包poster中的库提供的功能感兴趣tcolorbox。 它是以 为模型的baposter，但可以说具有更多功能。
