Question

I asked for help before and some person's helped me before and am grateful. But am stuck again. Have been trying to execute some functions with javascript but it's not just working. The only one that was able to work was the hamburger menu, expect from that nothing else. And also I Have to create an auto slider with javascript and have not done one before and I don't know how. Pls if there's anyway you'll be of assistance I'll appreciate, if it's a link to a video or write up or something for me to read, I love to learn it so that I'll be able to complete my project. Thanks. Here's what have done so far 👇 Chris Coder , Your Mom , Shobhit :)
