Bootstrap 5 navigation not wide as parent container-CodePudding

I have created a navigation in Bootstrap inside a container, but for some reason the navigation bar is not as wide as the container, but why? I even had to set padding of the navigation bar manually.

Code: index.php

   <!DOCTYPE html>
    <html lang="cs">
        <head>
            <title>xGhost.cz | Československý Gamehosting.</title>

style.css

.navbar {
    padding-left: 15px;
    padding-right: 15px;
    text-align: center;
}

.content, .login {

CodePudding user response：

You have to wrap the nav in a container whose class is row

container-lg has some positive margin-left and margin-right, but you have to add row whose margin-left and margin-right is negative, which nullify the effect of margin.

.navbar {
  padding-left: 15px;
  padding-right: 15px;
  text-align: center;
}

.content,
.login {
  background: #f0f0f0;
}
