Hey,
I know this post is pretty old but I am just starting with ionic and came across the same issue.
One solution I found was simply taken from another issue: Vertically center a button
HTML:
<ion-footer-bar class="bar-stable button-footer-bar">
<a class="button button-stable">Filtern</a>
</ion-footer-bar>
CSS:
.button-footer-bar {
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-webkit-box-direction: normal;
-moz-box-direction: normal;
-webkit-box-orient: horizontal;
-moz-box-orient: horizontal;
-webkit-flex-direction: row;
-ms-flex-direction: row;
flex-direction: row;
-webkit-flex-wrap: nowrap;
-ms-flex-wrap: nowrap;
flex-wrap: nowrap;
-webkit-box-pack: center;
-moz-box-pack: center;
-webkit-justify-content: center;
-ms-flex-pack: center;
justify-content: center;
-webkit-align-content: stretch;
-ms-flex-line-pack: stretch;
align-content: stretch;
-webkit-box-align: center;
-moz-box-align: center;
-webkit-align-items: center;
-ms-flex-align: center;
align-items: center;
}
Can someone say if there are any plattforms where this may not be working?
