It could be the fact that you wrapped all the images in a <p> tag ... All elements have default margins and padding so ... it might be that the padding and margin are affecting it.

Try resetting them.

If you want to reset all margin and padding to 0 for all the element you can do

Code: Select all

html, body, p, ul, ol, h1, h2, h3, h4, h5, h6 {
	margin: 0;
	padding: 0;
}

or

Code: Select all

* {
  margin: 0;
  padding: 0;
}

No Margin For Error
