The div is not aligning in the center after I added the nav bar to the top-CodePudding

I'm new to coding but I need a website soon, So I started working on it but once I added the nav bar the box with contents is not center anymore. I've tried to troubleshoot it and i have tried every single css line and none do the work of aligning the box to the center. Codepen

    .panel {
    background-color: #ffffff;
    border-radius: 10px;
    padding: 15px;
    width: 90%;
    max-width: 1000px;
    display: flex;
    align-items: center;
    flex-direction: column;
    text-align: center;
    text-transform: uppercase;
    border: 2px solid gray;
    background-position: center;
    margin-top: 20px;
    margin-bottom: 20px;
}

I've changed the body to display:flex and align-items:center. Seems to have done the trick. I've made a few other tweaks and commented them for your convenience

*,
*::after,
*::before {
  box-sizing: border-box;
  /* added this to remove some oddball positioning problems */
}

body {
  margin: 0;
  /* added this to remove the margin around the edge */
  display: flex;
  /* this makes the children divs type flexbox. */
  flex-direction: column;
  /* Stack divs on top of each other */
  align-items: center;
  /* Center items in the body */
}

#navbar {
  background-color: #787a7a;
  display: flex;
  justify-content: flex-end;
  /* height: 10vh; <-- won't scale properly at small screen heights*/
  /* position: cover; <--- invalid property*/
  width: 100%;
}

One simple solution is to use auto margins for margin-left and margin-right of your panel.

your panel class would be like this:

.panel {
    background-color: #ffffff;
    border-radius: 10px;
    padding: 15px;
    width: 90%;
    max-width: 1000px;
    display: flex;
    align-items: center;
    flex-direction: column;
    text-align: center;
    text-transform: uppercase;
    border: 2px solid gray;
    background-position: center;
    margin: 20px auto;
}
