How to add a background video to the homepage slider in Boundless theme?

Boundless is one of the most downloaded free themes from Shopify.

One of the outstanding features of this theme is its homepage image slider. 

You can take advantage of this feature and add a video to each slide with Video Background. 

It is possible to add videos to each slide easily using the following pattern:

.hero__slide:eq(N) > img 

where N is the index of the slide starting from 0.

If we want to put the video on the first slide, we have to write this selector:

.hero__slide:eq(0) > img 

and if we want to put the video on the third slide, we have to write this selector:

.hero__slide:eq(2) > img 

To do so, let's go to the app preferences page and tap on the  Add new video option.

Once on this page, make sure to select the  home page and Section Video Background options on the video location page, as well as to configure the selector mentioned before:

After this, you can click on  Save and continue and introduce the desired video URL on the following page:

Finally, the video should be properly visible on the desired position.

Note that it is important to keep the target slider fully transparent:

f we want to replace the entire slider, we can use this selector:
