`tcolorbox` background color change

tcolorbox

\documentclass[fleqn, 12pt] {article}
\usepackage{epsf}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{lipsum}
\usepackage{enumerate}
\usepackage[shortlabels]{enumitem}
\usepackage[dvips]{graphics}
\usepackage[dvipsnames]{xcolor}
\usepackage{fancyhdr}
\usepackage{blindtext}
\usepackage{color}
\usepackage[breakable]{tcolorbox}

\begin{document}
   There are too many sentences and hence the following box starts from the lower part of the page.
   \begin{center}
        \begin{tcolorbox}[breakable][colback=white, sharp corners]
            This text is quite large.
        \end{tcolorbox}
\end{center}
\end{document}

When I don't use breakable, the background becomes white but The text is quite large shifts to next page. Also the corners are sharp. But using breakable, the background becomes default color grey but The text is quite large is breaking into two pages. Also the corners become rounded.

I want to bring page breaking together with white background color and sharp corner using tcolorbox.

Best Answer

You should include all options into the single square brackets, e.g., you used as \begin{tcolorbox}[breakable][colback=white, sharp corners] but it should be as \begin{tcolorbox}[breakable,colback=blue!5, sharp corners], and the modified MWE is:

\documentclass[fleqn, 12pt] {article}
\usepackage{epsf}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{lipsum}
\usepackage{enumerate}
\usepackage[shortlabels]{enumitem}
\usepackage[dvips]{graphics}
\usepackage[dvipsnames]{xcolor}
\usepackage{fancyhdr}
\usepackage{blindtext}
\usepackage{color}
\usepackage[breakable]{tcolorbox}

\begin{document}
   There are too many sentences and hence the following box starts from the lower part of the page.
   \begin{center}
        \begin{tcolorbox}[breakable,colback=blue!5, sharp corners]
            This text is quite large.

\lipsum[1-5]
        \end{tcolorbox}
\end{center}
\end{document}

Apart from that, I'm not sure for what purpose you need \begin{center}...\end{center}, hope this is not necessary...
