                    <p class="main-header__txt"><i class="fa-solid fa-phone"></i> Call 12345678099</p>
                </div>   
                <div clas="main-header__container">
                <i class="fa-solid fa-user"></i>
                <a href="">My cart<i class="fa-solid fa-cart-shopping"></i></a>
                <input type="search"><i class="fa-solid fa-magnifying-glass"></i>
                </div> 
            </div>
        </header>
    </body>
</html>

an this is in css:

* {
  box-sizing: border-box;
}
body{
  margin :0;
}
img{
  display: block;
  width: 100%;
}
.main-header__title{
  text-align: center;
  font-size: 2.5em;
  margin: 10px 0px;
  color: #454546;
}
.main-nav{
  display: none;
}
.main-header__title{
  display: flex;
  justify-content: space-around;
  align-items: center;
}
.icon-menu{
  font-size: 1.5em;
  border: 1px solid #454546;
  display: block;
  padding: 10px 20px;
}

its supposed to watch like this

But, it looks like this

maybe its a problem on the display:flex or in the justify-content: space around. My real problem is that i don't know how to change this

thanks ;D

Solution

Errors were:

Typos in word "clas"
Use wrong class in CSS - ".main-header__title" instead of ".main-header__container"

Here is a solution:

* {
  box-sizing: border-box;
}

body {
  margin: 0;
}

img {
  display: block;
  width: 100%;
}

.main-header__title {
  text-align: center;
  font-size: 2.5em;
  margin: 10px 0px;
  color: #454546;
}

.main-nav {
  display: none;
}

.main-header__container {
  display: flex;
  justify-content: space-around;
  align-items: center;
}

.icon-menu {
  font-size: 1.5em;
  border: 1px solid #454546;
  display: block;
  padding: 10px 20px;
}
