Rotate an ionicon on the page

Question

I want to display directions with an arrow and was thinking to use the standard ionic arrow for the direction. Can I rotate the up arrow into any direction somehow?

ion-arrow-up-a

Here is an attempt from the comments below

<i class="icon ion-arrow-up-a" rotate degrees="90"></i>


angular.module('app.customDirectives', []).directive('rotate', function() {
      return {
            link: function(scope, element, attrs) {
                // watch the degrees attribute, and update the UI when it changes
                scope.$watch(attrs.degrees, function(rotateDegrees) {
//                  console.log(rotateDegrees);
                    //transform the css to rotate based on the new rotateDegrees
                    element.css({
                        '-moz-transform': 'rotate(' + rotateDegrees + 'deg)',
                        '-webkit-transform': 'rotate(' + rotateDegrees + 'deg)',
                        '-o-transform': 'rotate(' + rotateDegrees + 'deg)',
                        '-ms-transform': 'rotate(' + rotateDegrees + 'deg)'
                    });
                });
            }
    }
});

Answer 1

There is other variants of arrow:

ion-arrow-up-a
ion-arrow-right-a
ion-arrow-down-a
ion-arrow-left-a

Or... As I know, ionic framework is HTML5 based, so you can use CSS styles.

.style {
    -moz-transform: rotate(15deg);
    -webkit-transform: rotate(15deg);
    -o-transform: rotate(15deg);
    -ms-transform: rotate(15deg);
    transform: rotate(15deg);
}

If you want dynamic rotation, you have to check this url.

Answer 2

for some reason the <i> element has to own display: inline-block css style to rotate successfully:

controller code:

$scope.angle = 90

HTML:

<i class="ion-arrow-up-c" style="display: inline-block; transform: rotate({{angle}}deg);"></i>

Answer 3

For Ionic icons v1, v2 specifically, the rotate property works only with the display property set to "inline" or "inline-block", it might work with other variations of inline as well.

Then you can rotate them normally using CSS

transform: rotate(90deg);

Answer 4

Similar to above, this is how I did it...

HTML:

<i class="ion-arrow-up-c rotate-90">

CSS:

.rotate-90 {
  display: inline-block; 
  transform: rotate(90deg);
}
