How to align heading <h1> in the center of the page - html

Question

I want to center <h1> or <div class="heading"> on the page. The only solution I have found is
body { text-align: center; }
but I can't figure it out why this code doesn't work. Display: inline-block is used because I want the border to wrap around my .
body {
margin: 0;
}
.navbar {
text-align: right;
background: black;
color: white;
padding: 10px;
}
ul {
list-style-type: none;
padding: 5px;
}
li {
display: inline-block;
}
.heading {
border: 2px solid black;
display: inline-block;
text-align: center;
}
<header>
<nav class="navbar">
<ul>
<li>home</li>
<li>about</li>
<li>contact</li>
</ul>
</nav>
<div class="heading">
<h1>heading</h1>
</div>
</header>

Answer 1

Add this:
.heading {
text-align: center;
}
...and delete display: inline-block from .heading. Instead, add this
.heading h1 {
display: inline-block;
}
.heading is the container of your h1. Both are by default 100% wide. This centers the inline-block h1 inside the full-width .heading

The secret you are looking for is to use a block-level element, and also set a margin: 0 auto. This tells the block to centralise, much like a standard text-align: center.
.header {
display: block;
margin: 0 auto;
}
By default, block-level elements occupy 100% of the width of their container, so you might also want to specify a width for the header. Alternatively, you can have the header automatically adjust to the size of the text by adding a container div that is set as in inline-block, and moving the border to there:
body {
margin: 0;
}
.navbar {
text-align: right;
background: black;
color: white;
padding: 10px;
}
ul {
list-style-type: none;
padding: 5px;
}
li {
display: inline-block;
}
.heading {
display: block;
margin: 0 auto;
text-align: center;
}
.heading-wrapper {
display: inline-block;
border: 2px solid black;
padding: 0 10px;
}
<header>
<nav class="navbar">
<ul>
<li>home</li>
<li>about</li>
<li>contact</li>
</ul>
</nav>
<div class="heading">
<div class="heading-wrapper">
<h1>heading</h1>
</div>
</div>
</header>
This way, the header will stay centralised, and have the border automatically expand correctly to accommodate the header, no matter how much text there is.
Hope this helps! :)

You can center it by using display: flex; justify-content; on the parent element. Here is a great resource on centering things https://www.w3.org/Style/Examples/007/center.en.html
body {
margin: 0;
}
.navbar {
text-align: right;
background: black;
color: white;
padding: 10px;
}
ul {
list-style-type: none;
padding: 5px;
}
li {
display: inline-block;
}
.heading {
display: flex;
justify-content: center;
}
<header>
<nav class="navbar">
<ul>
<li>home</li>
<li>about</li>
<li>contact</li>
</ul>
</nav>
<div class="heading">
<h1>heading</h1>
</div>
</header>

a div displays block by default, so it's definitely important to declare if you want to display it otherwise.
However, again, as in another post i saw earlier, you have no css for the containing parent, the header, which would greatly assist you. You should apply any margin to be inherited to this, and there should be no need to apply a small width to your div.
body {
margin: 0;
}
header{margin: 0 auto;}
.navbar {
text-align: right;
background: black;
color: white;
padding: 10px;
}
ul {
list-style-type: none;
padding: 5px;
}
li {
display: inline-block;
}
.heading {
border: 2px solid black;
/*display: block; - even if you leave this out, it will display as block*/
text-align: center;
}
<header>
<nav class="navbar">
<ul>
<li>home</li>
<li>about</li>
<li>contact</li>
</ul>
</nav>
<div class="heading">
<h1>heading</h1>
</div>
</header>
