creating a star rating system based of an API

I have an api that will give a number of either 1-5 under "ratings" , i also have a list of 5 stars, depending on the rating these stars will either turn red or black on click of the button, red will be for each number in the Ratings . i.e a rating of 4 would turn 4 of the stars red and 1 black. so far i have the html and css created but when the button is pressed i recieve no data at all to test the button I added a basic alert and that worked. So far I have this:
DEMO:
$("#viewreview").click(function(){
$.ajax("api link").done(function(data){
$(".reviewblk").html('');
var htmlstr = '';
for(var i=0; i<data.length; i++){
var rating = parseInt(data[i]["rating"]);
var chk = ['', '', '', '', ''];
for(var j=0; j<rating && j<5;j++){
chk[j] = 'checked';
}
htmlstr += '<div class="preview"><img src="reviewicon1.jpg" alt="reviewpic" class="revImg" /><div class="stars"><p class="checked '+chk[0]+'"></p><p class="checked '+chk[1]+'"></p><p class="checked '+chk[2]+'"></p><p class="checked '+chk[3]+'"></p><p class="checked '+chk[4]+'"></p></div><h3 class="personName">'+data[i]["nickname"]+'</h3><div class="revtext"><p>'+data[i]["review"]+'</p></div></div><hr />';
}
$(".reviewblk").html(htmlstr);
});
})

Please consider the following.
$("#viewreview").click(function() {
$.ajax("api link").done(function(data) {
$(".reviewblk").html('');
var rating, preview, stars;
$.each(data, function(i, el) {
preview = $("<div>", {
class: "preview"
}).appendTo(".reviewblk");
$("<img>", {
src: "reviewicon1.jpg",
alt: "Review Icon",
class: "revImg"
}).appendTo(preview);
stars = $("<div>", {
class: "stars"
}).appendTo(preview);
rating = parseInt(el.rating);
for (var i = 1; i <= 5; i++) {
$("<p>", {
class: (i <= rating ? "checked" : "unchecked")
}).appendTo(stars);
}
$("<h3>", {
class: "personName"
}).html(el.nickname).appendTo(preview);
$("<div>", {
class: "revText"
}).html("<p>" + el.review + "</p>").appendTo(preview);
$("<hr>").appendTo(preview);
});
});
});
We can use jQuery to create the elements and append them as they are created. Using $.each(), we can itereate each of the items in data. WE also know there will be 5 'check' items, so we can simply create a small loop to create them. A number of them, equal to the rating will be "checked", so we can add a condition to check each one and mark it as needed.
For example, if the rating was 3, we would see:
<p class="checked"></p>
<p class="checked"></p>
<p class="checked"></p>
<p class="unchecked"></p>
<p class="unchecked"></p>
i will be 1 on the first iteration, and 1 is less than 3. On the 3rd loop, i will be 3 and will still meet the condition. When i is 4 or 5, it is no longer true so unchecked is supplied.

How to implement a card-view block same as this example html/css/js?

Just like this example build by tcoloredbox of latex.
My problems are:
how to make the title, the Loi image part, be adjusted by sentence length?
how to make the position of the title, still the Loi image part, has a changeable position? Can pure css work this out?
if I want the title sentence be changed when I click/hover the title, how should I do that?
Ok, I have relaize that the math equations are indeed a problem, here is a new post about the problem:

Trouble with slider arrows

I have a lot of trouble with my slider arrows as I am following along with a tutorial on youtube. Instead of going next to the picture and testimonial, it goes on the top. It didn't happen this way at first, but then I had a problem with glider.js, so I rewrote the code, and then the flaw appeared

This is because of how the css position property works more info
Try add this line and see if it helps:

How to vertically center dialog box at the its current scroll position

How would I be able to vertically center the dialog box at its current scroll position of the window when either one of the "show dialog" buttons is clicked?
Example: When I click the bottom on locations 3. I'm trying to get the dialog box to be vertically centered at that current viewing window screen. And this should be the case for all buttons.
$('.show-dialog-btn').click(function() {
$('#dialog-box').addClass('display-dialog-box');
});
$('.close-dialog-btn').click(function() {
$('#dialog-box').removeClass('display-dialog-box');
});
.locations-container {
padding: 10px
}
.locations-container:not(last-of-type) {
margin-bottom: 100px
}
.locations-container:nth-child(3) {
background: #eee
}
#dialog-box {
top: 50%;
left: 50%;
z-index: 99;
display: none;
width: 220px;
color: #4a4a4a;
position: absolute;
border-radius: 10px;
background: #fff;
padding: 10px;
transform: translate(-50%, -50%);
border: 1px solid rgba(0, 0, 0, 0.2);
box-shadow: 1px 5px 4px rgba(0, 0, 0, 0.1)
}
#dialog-box.display-dialog-box {

show drop menu outside the sidebar that has a scroll, but still in the same position as the anchor

Like facebook, when hover over the image of the friend it shows drop menu out side the left sidebar of friends,
I gave the drop menu position absolute with respective to the app itself (position: relative), but the problem is when scrolling down the menu appear below its anchor tag, how can I fix it ?
here is the sample of the code that I have,
can I implement this with pure css or I need JS ?
.App {
position: relative;
}
nav {
overflow: auto;
max-height: 700vh;
}
.dropMenu {
position: absolute;
}
<div className="App">
<nav>
<ul>
<li>
<a onClick={this.showDropMenu}> ... </a>
</li>
<div className="dropMenu"></div>
</ul>
</nav>
</div>

Use position: sticky;
.App{
position: sticky;
}
nav {
overflow: auto;
max-height: 700vh;
}
.dropMenu {
position: absolute;
}

This is the simplest way you can do it using only CSS. You may have to implement other behaviors if you want to have a fully functional dropdown-menu.
$(".nav li").on("mousemove", evt => {
const li = $(evt.target);
const dropdown = $(evt.target).find('.dropdown-menu');
let liTop = li.offset().top;
liTop = liTop < 0 ? liTop * -1 : liTop;
dropdown.css('top', liTop + li.height());
})
ul {
list-style: none;
overflow-y: auto;
height: 100px;
width: 400px;
}
ul li {
margin: 20px 0;
}
ul li:hover .dropdown-menu {
display: block;
}
ul li .dropdown-menu {
position: absolute;
display: none;
width: 300px;
background-color: #fff;
box-shadow: 0 6px 12px rgba(0, 0, 0, 0.2);
padding: 10px;
}
