I am using tumult hype animation wordpress plugin.
Some animations are not showing even I use same shortcode as others which is showing properly.
The source code of page was like <div id="koreanlettertable_hype_container" class="HYPE_document" style="margin:auto;position:relative;width:100%;height:100%;overflow:hidden;">
I guess the css script "overflow:hidden" causing the problem.
Why the plugin make script like this and how can I fix it?
Your assumption is most likely wrong, overflow hidden is not causing the problem. What is causing the problem is the setting of 100% height in the context of a parent DIV with no height. Meaning, if the container you embedded it in does declare some sort of height … Hype will be 100% of 0px.
The solution is to give:
Hype a height in the application (fixed value)
the surrounding DIV a height (fixed, or based on vh etc.) in your WordPress Builder of choice
