创建一个彩色盒子？

谁能用乳胶代码帮助我如何创建如下图所示的框？ 在此处输入图片描述

第二个框是

我尝试使用包{tcolorbox}，但没有成功。我想用那个颜色创建一个与图 1 完全相同的盒子！我想在图 1 中自动编号“Assumption SLR. xx”，在图 2 中自动编号“Example 1.xxx”

谢谢

改良版：

\documentclass{article}
\usepackage[many]{tcolorbox}
\usetikzlibrary{calc}

\definecolor{myblue}{RGB}{0,163,243}

\tcbset{mystyle/.style={
  breakable,
  enhanced,
  outer arc=0pt,
  arc=0pt,
  colframe=myblue,
  colback=myblue!20,
  attach boxed title to top left,
  boxed title style={
    colback=myblue,
    outer arc=0pt,
    arc=0pt,
    top=3pt,
    bottom=3pt,
    },
  fonttitle=\sffamily
  }
}

\newtcolorbox[auto counter,number within=section]{example}[1][]{
  mystyle,
  title=Example~\thetcbcounter,
  overlay unbroken and first={
      \path
        let
        \p1=(title.north east),
        \p2=(frame.north east)
        in
        node[anchor=west,font=\sffamily,color=myblue,text width=\x2-\x1] 
        at (title.east) {#1};
  }
}
\newtcolorbox[auto counter]{assumption}[1][]{
  mystyle,
  colback=white,
  rightrule=0pt,
  toprule=0pt,
  title=Assumption SLR.\thetcbcounter,
  overlay unbroken and first={
      \path
        let
        \p1=(title.north east),
        \p2=(frame.north east)
        in
        node[anchor=west,font=\sffamily,color=myblue,text width=\x2-\x1] 
        at (title.east) {#1};
  }
}

\begin{document}

\section{Test section}
\begin{example}
test
\end{example}
\begin{assumption}
test
\end{assumption}
\begin{example}[Optional title]
test
\end{example}
\begin{assumption}[Optional title with some more words for the example so it spans two lines]
test
\end{assumption}

\end{document}

第一个版本：

一种可能性是：

\documentclass{article}
\usepackage[many]{tcolorbox}

\definecolor{myblue}{RGB}{0,163,243}

\tcbset{mystyle/.style={
  breakable,
  enhanced,
  outer arc=0pt,
  arc=0pt,
  colframe=myblue,
  colback=myblue!20,
  attach boxed title to top left,
  boxed title style={
    colback=myblue,
    outer arc=0pt,
    arc=0pt,
    },
  title=Example~\thetcbcounter,
  fonttitle=\sffamily
  }
}

\newtcolorbox[auto counter,number within=section]{example}[1][]{
  mystyle,
  title=Example~\thetcbcounter,
  }
\newtcolorbox[auto counter]{assumption}[1][]{
  mystyle,
  title=Assumption SLR.\thetcbcounter,
  }

\begin{document}

\section{Test section}
\begin{example}
test
\end{example}
\begin{assumption}
test
\end{assumption}

\end{document}

我对示例和假设使用了相同的风格，但如果您还想重现其他风格，只需进行简单的修改即可：

\documentclass{article}
\usepackage[many]{tcolorbox}

\definecolor{myblue}{RGB}{0,163,243}

\tcbset{mystyle/.style={
  breakable,
  enhanced,
  outer arc=0pt,
  arc=0pt,
  colframe=myblue,
  colback=myblue!20,
  attach boxed title to top left,
  boxed title style={
    colback=myblue,
    outer arc=0pt,
    arc=0pt,
    },
  title=Example~\thetcbcounter,
  fonttitle=\sffamily
  }
}

\newtcolorbox[auto counter,number within=section]{example}[1][]{
  mystyle,
  title=Example~\thetcbcounter,
  }
\newtcolorbox[auto counter]{assumption}[1][]{
  mystyle,
  colback=white,
  rightrule=0pt,
  toprule=0pt,
  title=Assumption SLR.\thetcbcounter,
  }

\begin{document}

\section{Test section}
\begin{example}
test
\end{example}
\begin{assumption}
test
\end{assumption}

\end{document}
