Hi @dactou,
I hope you are well today and thank you for your questions.
1) The lines are so transparents, how can I increase the border or change the color in style.css?; I can’t find.
You can try achieving this by adding the following CSS code in the Custom CSS option of the latest version of Sparkling theme on the below path.
Admin Area -> Appearance -> Customize -> Sparkling Options -> Other -> Custom CSS
aside.widget ul li {
border-bottom: 2px solid #BF5C5C;
}
Please change the border size and color value in the above code to whatever you want to use by referring the following pages.

2)How can I change the color of the buttons of tags below a post?; i can’t find in style.css.
You can change the color of the buttons of tags below a post by using the following CSS code as described above.
div.tagcloud a {
background-color: #adbbc6;
color: #555 !important;
}
Change color value in the above code to whatever you want to use.
3) Can I remove this text: “Theme by Colorlib Powered by WordPress” in the footer?
Yes you can remove that text by using the attached child theme of Sparkling theme on the following thread.
