How to horizontally center grouped elements inside a navigation bar - html

Question

I am building a navigation bar that has a lot of options and special sections.
I worked with Twitter Bootstrap, but it is difficult to develop.
The nav html tag has 3 sections grouped in 3 divs (left, center, right).
I am having difficulty in centring horizontally the text and logo of the company in left div, anchors with navigation items in the right div.
I need the height of navigation bar to be set in the CSS and not the calculate the height based of the child elements.
This is the html:
.navbar {
overflow: hidden; /* Clips from content if it is bigger than the parent element */
background-color: #333;
position: fixed; /* Position of the navbar is fixed */
top: 0;
width: 100%;
height: 50px;
}
.left-navbar {
float: left;
background: cadetblue;
width: 230px;
height: 100%;
text-align: center;
}
.right-navbar {
float: right;
background: maroon;
height: 100%;
/* float: right;
position: absolute;
top: 50%; right: 0%;
transform: translate(-50%,-50%);
background: gold;
padding: 1.5rem; */
}
.center-navbar {
position: absolute;
top: 50%; left: 50%;
transform: translate(-50%,-50%);
background: gold;
padding: 1rem;
}
.left-navbar strong {
color: red;
padding: 10px 10px;
display:inline-block;
text-align: center;
vertical-align: center;
}
.left-navbar img {
width: 32px;
height: 32px;
padding: 10px 10px;
}
.navbar a {
float: right; /* Orientation of the element in the parent element */
display: block; /* All over top left right bottom it is a block - element has block/padding all over the embedded element */
color: #f2f2f2;
text-align: center;
padding: 14px 16px; /* 14px top and bottom, 16px right and left */
text-decoration: none; /* Could be underline, overline, line-through */
font-size: 17px;
}
/* Apply only for anchors inside the navbar class */
.navbar a:hover {
background: #ddd;
color: black;
}
input[type="text"]{ padding: 5px 5px; line-height: 28px; }

<div class="right-navbar">

Any working fiddle with best practices is ideal for me.
Thank you!

Answer 1

You can use flexbox to achieve this
.right-navbar, .left-navbar{
display: flex;
justify-content: center;
align-items: center;
}
Here you have a codepen, let me know if that help!

Answer 2

Give .left-navbar - horizontal and vertical centering with display:flex;
.left-navbar {
display: flex;
float: left;
background: cadetblue;
width: 230px;
height: 100%;
text-align: center;
justify-content: center;
align-items: center;
}
Also, how do you want the right part of the navbar?

Answer 3

Flex-box is what you'll want to use here. Add display: flex to the .navbar and then add flex-grow: 1; to the center piece. This essentially says 'make this element span the remaining space in the flex container. Also, your height: 100% were unnecessary, so I removed them.
.navbar {
overflow: hidden; /* Clips from content if it is bigger than the parent element */
background-color: #333;
position: fixed; /* Position of the navbar is fixed */
top: 0;
width: 100%;
height: 50px;
display: flex;
}
.left-navbar {
background: cadetblue;
width: 230px;
text-align: center;
}
.right-navbar {
background: maroon;
}
.center-navbar {
background: gold;
padding: 1rem;
flex-grow: 1;
}
input[type="text"]{
padding: 5px 5px;
line-height: 28px;
width: 100%;
box-sizing: border-box;
}
