I'm trying to align an HTML button exactly at the centre of the page irrespective of the browser used. It is either floating to the left while still being at the vertical centre or being somewhere on the page like at the top of the page etc..
I want it to be both vertically and horizontally be centered. Here is what I have written right now:
<button type="button" style="background-color:yellow;margin-left:auto;margin-right:auto;display:block;margin-top:22%;margin-bottom:0%">
mybuttonname
</button>
This question is related to

The answer is
try this it is quite simple and give you cant make changes to your .css file this should work
<p align="center">
<button type="button" style="background-color:yellow;margin-left:auto;margin-right:auto;display:block;margin-top:22%;margin-bottom:0%"> mybuttonname</button>
</p>
You can center a button without using text-align on the parent div by simple using margin:auto; display:block;
For example:
HTML
<div>
<button>Submit</button>
</div>
CSS
button {
margin:auto;
display:block;
}

There are multiple ways to fix the same. PFB two of them -
1st Way using position: fixed - position: fixed; positions relative to the viewport, which means it always stays in the same place even if the page is scrolled. Adding the left and top value to 50% will place it into the middle of the screen.
button {
position: fixed;
left: 50%;
top:50%;
}
2nd Way using margin: auto -margin: 0 auto; for horizontal centering, but margin: auto; has refused to work for vertical centering… until now! But actually absolute centering only requires a declared height and these styles:
button {
margin: auto;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
height: 40px;
}
Here is the solution as asked
<button type="button" style="background-color:yellow;margin:auto;display:block">mybuttonname</button>For me it worked using flexbox.
Add a css class around the parent div / element with :
.parent {
display: flex;
}
and for the button use:
.button {
justify-content: center;
}
You should use a parent div, otherwise the button doesn't 'know' what the middle of the page / element is.
Place it inside another div, use CSS to move the button to the middle:
<div style="width:100%;height:100%;position:absolute;vertical-align:middle;text-align:center;">
<button type="button" style="background-color:yellow;margin-left:auto;margin-right:auto;display:block;margin-top:22%;margin-bottom:0%">
mybuttonname</button>
</div>?
Here is an example: JsFiddle
Make all parent element with 100% width and 100% height and use display: table; and display:table-cell;, check the working sample.
<!DOCTYPE html>
<html>
<head>
<style>
html,body{height: 100%;}
body{width: 100%;}
</style>
</head>
<body style="display: table; background-color: #ff0000; ">
<div style="display: table-cell; vertical-align: middle; text-align: center;">
<button type="button" style="text-align: center;" class="btn btn-info">

</button>
</div>
</body>
</html>
I've really taken recently to display: table to give things a fixed size such as to enable margin: 0 auto to work. Has made my life a lot easier. You just need to get past the fact that 'table' display doesn't mean table html.
It's especially useful for responsive design where things just get hairy and crazy 50% left this and -50% that just become unmanageable.
style
{
display: table;
margin: 0 auto
}
In addition if you've got two buttons and you want them the same width you don't even need to know the size of each to get them to be the same width - because the table will magically collapse them for you.
(this also works if they're inline and you want to center two buttons side to side - try doing that with percentages!).
