Getting 'cannot read property' offsetwidth 'undefined bootstrap
I am getting offsetwidth
undefined despite adding an active class and also defining my jquery right above my js function. I have to use carousel for my job and I tried the layout in practice. My first active image is displayed and after I click next I get this error in the console and the images are not sliding.

Change this line in your HTML:
<div class="item-active">
to
<div class="item active">
This hyphen should not be there. If you need a class item-active
, add it after these two for example <div class="item active item-active">
. item
and the active
bootstrap classes are used to run the carousel. Without them, on this first slide, you'll get this error.
