Why is footer not taking 100% width?

July 26, 2024

I have this simple React app and my footer does not take 100% width (I see small white space on the left and right sides). Can anyone tell me what I’m missing, please?

Here’s LIVE DEMO

Here’s my css:

.App {
  min-height: 100vh;
  display: flex;
  flex-direction: column;
}

.footer {
  margin-top: auto;
  background-color: #000;
  color: #fff;
  height: 50px;
  display: flex;
  justify-content: center;
  align-items: center;
  font-size: 12px;
  padding: 25px 0;
}

App.tsx

  return (
     <div className="App">
       <Footer />
     </div>
    );

>Solution :

The body element has a default 8px margin, have you removed it? If not, you can simply add to you .css file the following code:

body {
  margin: 0px;
}

Hope it helps you, if this is not your case feel free to comment here with more details.
Update: I tried adding it to your codesandbox and it worked here for me.
