自定义此标题页的垂直间距

Question

最近我发现了这篇文章，其中用户展示了精彩的标题页：

展示用 TeX 制作的精美标题页

我尝试过对将网站（如图所示）放在页面底部进行小幅调整，但失败了。有人能帮我实现吗？

\documentclass[10pt, a4paper]{report}
\usepackage{geometry}
\usepackage{xcolor}
\usepackage{graphicx}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\definecolor{titlepagecolor}{cmyk}{1,.60,0,.40}
\definecolor{namecolor}{cmyk}{1,.50,0,.10}

%-----------------------------------------------------------------
\begin{document}
    % ----------------------------------------------------------------
    \begin{titlepage}
        \newgeometry{left=5cm} %defines the geometry for the titlepage
        \pagecolor{titlepagecolor}
        \noindent
        \includegraphics[width=3cm]{logo.png}\\[-2 em]
        \color{white}
        \makebox[0pt][l]{\rule{1.3\textwidth}{1pt}}
        \par
        \noindent
        \Large \textbf{\textsf{Differential Equations}} %\hspace{0.1cm} \textcolor{namecolor}{\textsf{Material didático}}
        \vfill
        \noindent
        {\huge \textsf{1 - Big Topic}}
        \vskip\baselineskip
        \noindent
        \par
        \textsf{1.1 - Subtopic}
        \vskip\baselineskip
        \noindent
        \vskip\baselineskip
        \begin{center}
            \textsf{www.website.com}
        \end{center}

    \end{titlepage}
