问题
So... this is starting to annoy me ... and I thought i would come here and get some help..
The main div around the box has a width... then there is text... and a button that i want in the center of the div..
it is a <a href> button.. but it wont center.
I didn't think I would need to specify a width since the outside div has a width.. i tried margin:0 auto; text-align:center etc nothing works
<h2 class="service-style color_service">Annoyed</h2>
<div class="service-text text1">

</div>

回答1:
You have the problem because of the display:inline-block...see here
In this section of css,add:
Remove all the margin's set at buttonclass and amend as below:
/* --------------------------------------------------
:: Button Configuration
-------------------------------------------------- */
.button {
display:block; /* change this from inline-block */
width:20%; /* setting the width */
margin:0 auto; /* this will center it */
position:relative;
font-style:normal;
font-weight:normal;
font-family:"Open Sans";
font-size:14px;
outline:none;
color:#fff;
border:none;
text-decoration:none;
text-align:center;
cursor:pointer;
-webkit-border-radius:2px;
-moz-border-radius:2px;
border-radius:2px;
background-color:#96aa39;
border-bottom:1px solid #7b8b2f;
}
EDIT : to use inline-block without setting a width
inline-block demo
How to do only solution to center inline-block element is to use text-align:center
in your css class:
.service-text {
text-align: center; /* add this to center the button */
}
and then add:
.service-text p{
text-align:left /* and then add this to left align the text inside the para*/
}
this way you wont need to give width and only padding would solve your problem!
回答2:
Your button needs to be a block level element. Simplest fix:
a.button-large{
padding : 15px 30px 14px 30px;
margin : 5px auto;
display : block;
width : 100px;
}

I would also delete the 10px right margin on a.button-large i to center the "Learn More" text.
回答3:
You need to put the text-align:center; to the parent element of the button in your case is the div.service-text.
if you want the top P to be text-align:right; please use diffrent P to the button
remember. if your element is display:block; so you need to give margin: 0 auto; to your element. if your element is display:inline-block; you need to give text-align:center; to the parent element.

check fiddle here
you have to modify your css like below:
- remove margin from a.button-large class
- and change display:table in .button class
a.button-large{
padding:15px 30px 14px 30px;
}
.button{
display:table;
position:relative;
font-style:normal;
font-weight:normal;
font-family:"Open Sans";
font-size:14px;
margin:0 auto;
outline:none;
color:#fff;
border:none;
text-decoration:none;
text-align:center;
cursor:pointer;
-webkit-border-radius:2px;
-moz-border-radius:2px;
border-radius:2px;
}
回答5:
Quick way is to add "text-align: center;" to .service-text.
回答6:
I would suggest dialing it back a little and divorce yourself from your framework or whatever you are using. To center things horizontally there are 2 approaches.
You have to decide based on whether you want the button to be position: inline, inline-block, or block. For mobile and fingers and all that stuff(2014) - I would suggest inline-block or block. So -
if it's inline block, then you can just treat it like text. Set the parent to text-align center;
If it's block, then you you can use margin-right: auto; margin-left: auto; but that has other issues. Like all the other thinks near it need to be organized properly so that they don't float all over each other and screw everything up. I would suggest you do it like this: jsfiddle
PS - we don't need to see so much code in your fiddle. It's easier to get to the rout of the problem with only the bare necessities. Good luck.

Wrap the button in an element and give it text-align:center.
Write:
<div class="center">
<a href="" class="button button-large"><i class="fa fa-credit-card" style="padding-right:10px;"></i> Learn More</a>
</div>
.center {
text-align:center;
