Yeah, just use plugins ! Let me tell my story guys, I generally always wanted to know how you can easily create your own website with cool plugins. And my friend has been making cool websites for schools and universities for a couple of years. I asked him where he learned such sites and he replied that he came across https://stylemixthemes.com/cost-calculator-plugin/ and immediately started making very cool sites, and by the way, he always uses the most top plugins and his sites look just perfect. Well, in short, I have been learning how to make websites for more than six months, and I advise everyone.
