Can someone please help me? thank you.

Answer 1

It can't be positioned as absolute. Remove that. Make sure its parent has 100% width and then set margin:0 auto;

Answer 2

You could put your entire ribbon inside a divide. Then instead of centering the ribbon just give it a width of 100%.
ribbon_divide {
margin: 0 auto;
width: 90%;
}

Answer 3

You should wrap ribbon element and set width=100% for ribbon.
.ribbon-wrapper {
position: relative;
width: 90%;
margin: 0 auto;
}
.ribbon {
width: 100%
}
<div class="ribbon-wrapper">
<!-- Your ribbon html code -->
</div>

Answer 4

Just wrap your ribbon with a div.
<div style="width:90%;margin:0 auto;">
<div class="ribbon"><div class="ribbon-stitches-top"></div><strong class="ribbon-content"><h1>Xclo.mobi</h1></strong><div class="ribbon-stitches-bottom"></div></div>
</div>

Answer 5

You could actually center it based on percentage and absolutely:
.ribbon {
position: absolute;
width: 90%;
left: 50%;
margin-left: -45%;
}
