white spaces on the all sides [closed]

Your css file clearly shows a max-width of 1020px it appears as if your zoomed out or just on a large screen from your screenshot. If your window is bigger then 1020px then obviously there would be white space on either side.

.container{
  width: 100%;
  max-width: 1020px;
  margin: auto;
}

Also important to note this is not a wordpress issue
