hi dear
I had create a CSS style for my container,and this flex container also bind this style,however this style not works in deed, could you please provide best solution
click on the save button
If the save button doesn't fix it, copy/paste all of your styles from the styles folder into a text editor and look for invalid CSS. When you select copy styles from the designer it copies the CSS code to the paste buffer.
I had some styles that worked in an older Ignition but had bonus semicolons in a newer Ignition. I systematically updated the styles to make them work properly in the newer one.
