I'm trying to center a heading both vertically and horizontally inside a div that is rotated 45deg (transform:rotate(45deg);
).
Because the div is rotated - I rotate the heading the opposite direction (transform:rotate(-45deg);
) and then apply regular centering techniques which doesn't work. What is the solution for this?
#wrap {
position: relative;
transform: rotate(45deg);
top: 150px;
background-color: blue;
height: 300px;
width: 300px;
margin:0 auto;
}
h1 {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
transform: rotate(-45deg);
}
<html>
<body>
<div id="wrap"><h1>some centered text</h1></div>
</body>
</html>

You can achieve this by encapsulating your h1
in another div
#wrap {
position: relative;
transform: rotate(45deg);
top: 150px;
background-color: blue;
height: 300px;
width: 300px;
margin: 0 auto;
}
#text {
position: absolute;
height: 300px;
width: 300px;
transform: translate(-50%, -50%);
transform: rotate(-45deg);
background-color: red;
}
h1 {
text-align: center;
line-height: 300px;
margin: 0; /* H1 has default margin, read more: https://www.w3.org/TR/html-markup/h1.html *
}
<html>
<body>
<div id="wrap">
<div id="text">
<h1>some centered text</h1>
</div>
</div>
</body>
</html>

In your h1
element you defined this style
h1 {
...
transform: translate(-50%, -50%);
transform: rotate(-45deg);
}
you're overriding the first transform
property with the rotate()
and doing so you're losing the centering effect obtained by the negative translate()
: you should chain instead the two transformation like so
h1 {
position: absolute;
top: 50%;
left: 50%;
margin: 0;
transform: translate(-50%, -50%) rotate(-45deg);
}
You should also remove the default margin
applied on the h1
element (edit the demo and see what happens without margin: 0;
)

If you're happy to fix the height/width of your h1 elements, something like this will do it:
h1 {
position: absolute;
top: 50%;
left: 50%;
transform: rotate(-45deg);
height: 120px;
line-height: 40px;
width: 150px;
margin-top: -60px;
text-align: center;
margin-left: -75px;
}

use this transform: translate(-50%, -50%) rotate(-45deg);
#wrap {
position: relative;
transform: rotate(45deg);
top: 150px;
background-color: blue;
height: 300px;
width: 300px;
margin:0 auto;
}
h1 {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%) rotate(-45deg);
}
<html>
<body>
<div id="wrap"><h1>some centered text</h1></div>
</body>
</html>

You should write one transform
function right after another
I made a small change in your css, also added text-align: center;
transform: rotate(-45deg) translate(0, -100%);
#wrap {
position: relative;
transform: rotate(45deg);
top: 150px;
background-color: blue;
height: 300px;
width: 300px;
margin:0 auto;
}
h1 {
position: absolute;
top: 50%;
left: 50%;
transform: rotate(-45deg) translate(0, -100%);
text-align: center;
}

<div id="wrap"><h1>some centered text</h1></div>
