Hi, You can use this css code to increase width of this element. Add this code in appearance>> customize>> custom css

Hi, For tablet view use this css code-

    .single-course .course_header5_sideblock .course_details ul li {
    min-width:250px !important;

Hi, For button text in center please add this css code in appearance>> customize>> custom css

.single-course.course .course_header5_sideblock div#course-pricing a.course_button.full.button {

B,C- When I checked it was inside the block but you can decrease the width little bit from the code I provided you earlier. In that code you had to set the width as per your need. https://prntscr.com/10hrpci
