Centering a span inside a div - html

Question

I have a rotating text slider on my website that uses keyframe transitions.
I have all the text centered but the text inside the span sits to the side and I have tried everything I can think of to center it with no job.
/*Sentence*/
.sentence{
color: #999;
font-size: 3em;
text-align:center;
}
/*Wrapper*/
.wrapper{
font-family: serif;
text-align:center;
position: relative;
width: 100%;
}
/*Vertical Sliding*/
.slidingVertical{
display: inline;
}
.slidingVertical span{
animation: topToBottom 12.5s linear infinite 0s;
-ms-animation: topToBottom 12.5s linear infinite 0s;
-webkit-animation: topToBottom 12.5s linear infinite 0s;
color: #00abe9;
opacity: 0;
overflow: hidden;
position: absolute;
}
.slidingVertical span:nth-child(2){
animation-delay: 2.5s;
-ms-animation-delay: 2.5s;
-webkit-animation-delay: 2.5s;
}
.slidingVertical span:nth-child(3){
animation-delay: 5s;
-ms-animation-delay: 5s;
-webkit-animation-delay: 5s;
}
.slidingVertical span:nth-child(4){
animation-delay: 7.5s;
-ms-animation-delay: 7.5s;
-webkit-animation-delay: 7.5s;
}
.slidingVertical span:nth-child(5){
animation-delay: 10s;
-ms-animation-delay: 10s;
-webkit-animation-delay: 10s;
}
/*topToBottom Animation*/
#-moz-keyframes topToBottom{
0% { opacity: 0; }
5% { opacity: 0; -moz-transform: translateY(-50px); }
10% { opacity: 1; -moz-transform: translateY(0px); }
25% { opacity: 1; -moz-transform: translateY(0px); }
30% { opacity: 0; -moz-transform: translateY(50px); }
80% { opacity: 0; }
100% { opacity: 0; }
}
#-webkit-keyframes topToBottom{
0% { opacity: 0; }
5% { opacity: 0; -webkit-transform: translateY(-50px); }
10% { opacity: 1; -webkit-transform: translateY(0px); }
25% { opacity: 1; -webkit-transform: translateY(0px); }
30% { opacity: 0; -webkit-transform: translateY(50px); }
80% { opacity: 0; }
100% { opacity: 0; }
}
#-ms-keyframes topToBottom{
0% { opacity: 0; }
5% { opacity: 0; -ms-transform: translateY(-50px); }
10% { opacity: 1; -ms-transform: translateY(0px); }
25% { opacity: 1; -ms-transform: translateY(0px); }
30% { opacity: 0; -ms-transform: translateY(50px); }
80% { opacity: 0; }
100% { opacity: 0; }
}
<section class="wrapper">
<div class="sentence">
<p>header text - why use our service</p>
<div class="slidingVertical">
<span style="color:white; background:#018fcf">Best service on the market</span>
<span style="color:white; background:#0e7dcb">reason 1</span>
<span style="color:white; background:#1977B0">Long reason 2 - best value for money</span>

Also as you will see, the span doesnt fit to the size of the text and forces the text to wrap.
I have tried increasing the div and span to 100% width but that seems to decrease it to 0 for some strange reason.

Answer 1

It's because you position your spans absolutely - you need to center that absolute by adding left:50% and translating the x back -50%
I have also added position relative to your container:
/*Sentence*/
.sentence{
color: #999;
font-size: 3em;
text-align:center;
}
/*Wrapper*/
.wrapper{
font-family: serif;
text-align:center;
position: relative;
width: 100%;
}
/*Vertical Sliding*/
.slidingVertical{
position:relative;
}
.slidingVertical span{
animation: topToBottom 12.5s linear infinite 0s;
-ms-animation: topToBottom 12.5s linear infinite 0s;
-webkit-animation: topToBottom 12.5s linear infinite 0s;
color: #00abe9;
opacity: 0;
overflow: hidden;
position: absolute;
left: 50%;
transform: translate(-50%, 0);
}
.slidingVertical span:nth-child(2){
animation-delay: 2.5s;
-ms-animation-delay: 2.5s;
-webkit-animation-delay: 2.5s;
}
.slidingVertical span:nth-child(3){
animation-delay: 5s;
-ms-animation-delay: 5s;
-webkit-animation-delay: 5s;
}
.slidingVertical span:nth-child(4){
animation-delay: 7.5s;
-ms-animation-delay: 7.5s;
-webkit-animation-delay: 7.5s;
}
.slidingVertical span:nth-child(5){
animation-delay: 10s;
-ms-animation-delay: 10s;
-webkit-animation-delay: 10s;
}
/*topToBottom Animation*/
#-moz-keyframes topToBottom{
0% { opacity: 0; -moz-transform: translate(-50%, -50px); }
5% { opacity: 0; -moz-transform: translate(-50%, -50px); }
10% { opacity: 1; -moz-transform: translate(-50%, 0px); }
25% { opacity: 1; -moz-transform: translate(-50%, 0px); }
30% { opacity: 0; -moz-transform: translate(-50%, 50px); }
80% { opacity: 0; -moz-transform: translate(-50%, 50px); }
100% { opacity: 0; -moz-transform: translate(-50%, 50px); }
}
#-webkit-keyframes topToBottom{

100% { opacity: 0; -webkit-transform: translate(-50%, 50px); }
}
