Unknown Margin. Normalize.css Doesn't help.

There is a margin being added to divs and I don't know where it is coming from. I have a normilize.css file but that doesn't seem to work. You can find My code below.

<!DOCTYPE html> <html> <head> <link rel="stylesheet" type="text/css" href="css/style.css"> <link rel="stylesheet" type="text/css" href="normalize.css"> </head> <body> <div style="width:33%; height: 75px; background-color: red; display: inline-block; margin: 0px;"></div> <div style="width:33%; height: 75px; background-color: red; display: inline-block; margin: 0px;"></div> <div style="width:33%; height: 75px; background-color: red; display: inline-block; margin: 0px;"></div> </body> </html>

If you want it to take the whole 100% width the width needs to be set to 33.33%. Other than that if you have a live version to fiddle with than that could help me find what is the extra margin coming from.

I posted my fiddle below. Still getting this odd space in between. https://jsfiddle.net/cckske8r/

As I suspected but didn't want to say, the whitespace between divs gets added. Removing the space.

You have two options,

  1. Removing white space while it still has inline-block or
  2. Remove inline-block and use float:left

Hey Jacob,

to set the margin of your divs to 0 you can write it like that in your CSS:

div {
  margin: 0;
}

Note that you have to write the value of 0 without a value like px. Oh and also note that you should link to your normalize.css file before linking to your own styles in style.css because otherwise the styles in normalize.css will eventually overwrite your own styles.

I hope that helps!

This still isn't working but thanks for the tip about order.
