Why don't the color of the buttons on the slider change?

Question

css

I use the lightslider slider, in DevTools I found classes that are responsible for the styles of the slider buttons, and if you add these classes to style.css, then nothing happens except for !important, but then it applies to all sliders. How to change the color of the scroll buttons of the slider for only one slider, and not for all.

.blog-slider {
.lSSlideOuter .lSPager.lSpg > li a{
background-color:  red;
}
}

Answer 1

background-color: #000000; and not color, if you change for points
, and if you need to show numbers on them, then change text-indent and height
