So the plugin is using the grid-container
class in its CSS without any prefix. Which is going to effect a lot of themes.
The culprit CSS is this:
.grid-container {
width: 100%;
padding-right: 15px;
padding-left: 15px;
margin-right: auto;
margin-left:auto
}
And the problem is they specify the 100% width. So to overcome that you will need to add this CSS:
body .grid-container {
width: auto;
}
Just to let you know we are releasing our own block plugin:
