I would like to modify title chapter from vertical shape to horizontal with : based on titlesec package within book class, for example:

                         CHAPTER 1:   INTRODUCTION

and make it appear in the Table of Contents with bold number as:

   CHAPTER1: INTRODUCTION                                      1

Moreover, I have problem with adding : in List of Figures as:

Figure 1.1:

The following code for vertical space between chapter number and chapter title:

% chapters


we implicitly get:

                              CHAPTER 1

Use the block style. This code should do what you want for chapter headings:


As to the table of contents, you can do what you want with the titletoc package.

  • @Work: I didn't test the code, as you didn't post a full compilable example. The begingroup .. \endgroup construction is to limit the singlepacing directive scope? – Bernard Oct 3 '17 at 17:25
  • +1 , Many thanks. but give error with {\begingroup\singlespacing\MakeTextUppercase} [\endgroup], so its replace by {\begin{singlespace}\MakeUppercase} [\end{singlespace}]. Also, give me error. do you have idea to fix it without replace with {}. thanks again. – workwolf Oct 3 '17 at 17:31
