Only rendering the first div within the body

See original GitHub issue

After trying to find out why it’s doing this I cannot figure it out. My HTML renders correctly in a browser however once I try using this library to convert it into an image it will only render the first div. Any ideas why it’s doing this? `

@Nicholas-Ingram The problem arrived due to screen resolution and since the screen is not browser’s screen so it is unable to show responsiveness of bootstrap as browser does by adjusting the elements accordingly.I think your screen is not compatible with bootstrap’s high resolution css classes.I have changed col-lg to col-xs (even col-sm will work fine since these twos works on device having low width & height) and it is working fine for me.I am Attaching the code in the issue_discussion.docx file which will generate the image which you are looking for by replacing col-lg with col-sm and col-xs.
