white or other text readable? Filters?
Have you tried to solve the problem is not with the filter and lines? For example on any background to make the text readable?
Use CSS text-shadow
As an example the header on the video here:
Yes , the text shadow that visibly improves the readability, thank you, and how to make a blue film on the pictures, the filters are the same? there is no example at hand unfortunately - Bart25 commented on July 9th 19 at 14:14
