Can't get rid of white margin on div's

239 views Asked by Daniel At 12 September 2024 at 05:09

So, I have tried everything I can think of to get rid of the white margins around everything on my page.

I have put: margin: 0; on everything I can think of and it still does not get rid of it. Any help would be great!

I apologize for the giant wall of code.

function myFunction() {
  var x = document.getElementById("myTopnav");
  if (x.className === "topnav") {
    x.className += " responsive";
  } else {
    x.className = "topnav";
  }
}

/* global */

* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}

html {
  margin: 0;
  padding: 0;
  width: 100%;
  height: 100%;
  font-family: sans-serif;
}

body {
  margin: 0;
  padding: 0;
  width: 100%;
  height: 100%;
  font-family: "Tahoma", sans-serif;
  font-size: 16px;
  color: #454545;
  background-color: #fff;
}

div {
  margin: 0;
}


/* end global */


/* custom */

.container {
  padding-right: 15px;
  padding-left: 15px;
  margin-right: auto;
  margin-left: auto;
}

.footer {
  padding: 5px 10px;
  background-color: #428cd9;
}


/* end custom */


/* custom responsive */

.row::after {
  content: "";
  clear: both;
  display: block;
}

[class*="col-"] {
  float: left;
  padding: 15px;
}

.col-1 {
  width: 8.33%;

You're wrapping many elements in a .col-12 class. All .col- elements are set in your CSS to contain 15px of padding around the edges. Here's a screenshot from inspecting the page in Chrome Developer Tools where you can see the element highlighted:

You need to set padding to 0 on the col-12 element.

change the following in your CSS

.col-12 {
    width: 100%;
}

to

.col-12 {
    width: 100%;
    padding: 0px;
}

If you inspect the element, you can find that the unwanted space is because of the following style which applies padding to all elements with the class value containing col-.

[class*="col-"] {
  float: left;
  padding: 15px;
}

Override the style and you can get rid of the unwanted space. Note that this will set the padding to 0 for all the classes whose value contains col-.

[class*="col-"] {
  padding: 0;
}

Or you can only override the padding of .col-12 which will apply padding of 0 to .col-12 while the other classes containing col- will still get a padding of 15px.

.col-12 {
  padding: 0;
}
