Problem with opening HTML, CSS and JavaScript files (elements moved)

When I created my html, css and javascript files for the first time, they was located on desktop. Then decided to move all three files to another folder which located on disk D: and to rename the html file. Then, I opened my html file and noticed that my work is no longer in the same condition as it was before. Some elements are moved(see screenshot) and there one of the images is removes(there is an alternative text instead of the image). What should I do to return my work to the original status? Thanks, a lot for your help IMAGE
