CSS CSS Layout Basics Page Layout with the Float Property Creating a Horizontal Navigation with Floats

Some questions about aligning the navigation list on the same line

So I was trying to follow the instructions of aligning the navigation list on the same line in the header. In the video, the float:left property was used in the .main-nav li{} to align the navigation list horizontally. I tried to use the display: inline-block instead of the float:left property and got the same results. Whats the difference? Both ways are acceptable?

Here below is my code

/* ================================= 
  Base Styles
==================================== */

* {
    box-sizing: border-box;
}

body {
    font-family: 'Varela Round', sans-serif;
    line-height: 1.6;
    color: #3a3a3a;
}

p {
    font-size: .95em;
    margin-bottom: 1.5em;
}

h2,
h3,
a {
    color: #093a58;
}

h2,
h3 {
    margin-top: 0;
}

a {
    text-decoration: none;
}

/* ================================= 
  Base Layout Styles
==================================== */

/* ---- Navigation ---- */

.name {
    font-size: 1.25em;
}

.name,
.main-nav li {
    text-align: center;
    background: #fff;
    margin-top: 6px;
    margin-bottom: 6px;
}

.name a,
.main-nav a {
    padding: 10px 15px;
    text-align: center;
    display: block;
}

    .main-nav a {
        font-size: .95em;
        color: #3acec2;
        text-transform: uppercase;
    }

    .main-nav a:hover {
        color: #093a58;
    }

/* ---- Layout Containers ---- */

.container {
    padding-left: 1em;
    padding-right: 1em;
}

.main-header {
    padding-top: 1.5em;
    padding-bottom: 1.5em;
    background: #3acec2;
    margin-bottom: 30px;
}

.main-footer {
    text-align: center;
    padding: 2em 0;
    background: #d9e4ea;
}

/* ================================= 
  Media Queries
==================================== */

@media (min-width: 789px) {

    .wrap {
        min-height: calc(100vh - 89px);
    }

    .container {
        width: 85%;
        max-width: 1150px;
        margin: 0 auto;
    }

  .main-nav{
    float:right;
  }

  .main-nav li{
    margin-left: 12px;
    display: inline-block;
  }

  .name{
    float:left;
  }

    .feat-img {
        width: 300px;
    float:right;
    margin-left: 25px;
    margin-bottom: 25px;
    }

}

:point_right: There is rarely just one way to do something in CSS.

Floating removes an item from normal inline flow entirely, but inline-block allows it to remain in the flow but not require an entire line. For a given window width, the effect may be the same, but you might see some differences at different window sizes.

There could be performance concerns that might make one method preferable. But since layout is all about achieving a particular appearance, if it looks and functions the way you intended, it's acceptable.

Yes I was having the same concerns when completing the "float challenge". The fact that floats had just been taught, I went for two floats for the nav items (ul right and li left). I eventually got it after clearing up some issues with top alignment with the name but the teacher had done exactly as you had. One teacher I saw recently said "the right way is the way that works!". Those out the with mild OCD would disagree I'm sure but it did reassure me. Just make sure to test it out in as many ways as you can to check.
