如何模拟 Libretexts 数学站点中的数学环境？

Question

我在自由文本数学站点。我想在 latex 使用mdframed和tcolorbox包中模仿这些样式和结构。

\documentclass{article}
\usepackage{graphicx}
\usepackage[most]{tcolorbox}

% Define a new environment for LibreTexts-style math
\newtcolorbox{libremath}[1][]{
    colframe=blue!30,
    colback=white,
    rounded corners,
    title={#1},
    attach title to upper,
    coltitle=blue!70,
    boxed title style={
        colframe=blue!30,
        colback=white,
        outer arc=0pt,
    },
    fonttitle=\bfseries,
    before upper={\parindent0pt},
    after=\par\smallskip,
}

\begin{document}
    
    \begin{libremath}[]
        \includegraphics[width=1cm]{example-image-a}
        Solve the equation for $x$:
        \[ ax^2 + bx + c = 0 \]
    \end{libremath}
    
\end{document}

Answer 1

首先要说的是：

\documentclass{article}
\usepackage{graphicx}
\usepackage[most]{tcolorbox}
\usepackage{fontawesome}

% Define a new environment for LibreTexts-style math
\newtcolorbox{libremath}[2][]{
    enhanced,
    colframe=green!30!black,
    colback=green!20,
    sharp corners,
    attach boxed title to top left={yshift*=-\tcboxedtitleheight},
    title={\faCubes~#2},
    toprule=0pt, rightrule=0pt,bottomrule=0pt,
    coltitle=white,
    colbacktitle=green!30!black,
    boxed title style={
        sharp corners,
    },
    fonttitle=\bfseries,
    #1
}

\begin{document}
    
    \begin{libremath}{some title}
        \includegraphics[width=1cm]{example-image-a}
        Solve the equation for $x$:
        \[ ax^2 + bx + c = 0 \]
    \end{libremath}
    
\end{document}

更新

由于所有框都遵循类似的设计，因此它们可以采用通用样式但具有特定颜色和名称。接下来是每种框的定义及其特定的颜色、图标和名称。

定义和定理使用newtcbtheorem定义，它们将有两个强制参数，即定理标题和标签后缀。两者都可以声明为空，但必须出现。

\documentclass{article}
\usepackage{graphicx}
\usepackage[most]{tcolorbox}
\usepackage{fontawesome}

% Define a new environment for LibreTexts-style math
\tcbset{
    libretext/.style={
        enhanced,
        sharp corners,
        attach boxed title to top left={yshift*=-\tcboxedtitleheight},
        colframe=#1!30!black,
        colback=#1!20,
        colbacktitle=#1!30!black,
        toprule=0pt, rightrule=0pt, bottomrule=0pt,
        coltitle=white,
        fonttitle=\bfseries,
        boxed title style={sharp corners}
    }
}
