Hello,

I have visited your website and the bottom category’s color is changing.

And to add a stroke to the title try adding the following Custom CSS.

h1.entry-title.title {
    -webkit-text-stroke: 2px darkgrey;
    -webkit-text-fill-color: red;
    -webkit-animation: fill 0.5s infinite alternate;
}

Best Regards
