Practice-9

Hello!

Your coding of design is excellent. (I like your History Back style!)

I'd like to add a few js issues to the above:

-- "blur" event does not work properly with button elements, at least in Safari /Version 16.6/. I suggest to do inactive-button.classList.remove("selected") for all buttons inside a "click" callback-function of the active element (like @RalfiSlask noticed)

-- it's better to use add/remove(class) instead of toggle(). When the user clicks the same number twice, toggle() switches off the active mode.

It may seems overwhelming today, but don't give up and keep up! In case you get into this, I'd like to recommend a really good source for web-development learning - www.w3schools.com

Hey , I think @RalfiSlask rectified your errors regarding JS , I saw some problems with CSS and thought I should help . . .

• In your submit button as well .rate you should set font-family:inherit so that it goes along with the rest of the page , buttons and other input elements do not generally inherit it directly but rather have to be specified otherwise they display default font i.e., Arial

• NOT using commas to add styles to multiple elements/hover states . . . like this might function properly but shows error in editor so yea . . . .

.submit:visited{}
.submit:hover {background-color: hsl(0, 0%, 100%); color: hsl(25, 97%, 53%);}
.submit:active {}

The code should have been

.submit:link ,
.submit:visited,
.submit:active ,
.submit:hover {background-color: hsl(0, 0%, 100%); color: hsl(25, 97%, 53%);}

The site is ok otherwise . . .Hope I was able to help, happy coding!!! 🥂🥂

Variable Names

Change the name of btn to buttons as it targets all the buttons and not a single one, dont be afraid of writing larger names as it is important for other programmers to be able to understand your names. For example bck can be really hard to understand what it means.

Selectors

Have all the selectors at the top of your file.

Using var instead of let and const

I would suggest using the more common standard let and const for declaring variables as var is a bit outdated. It is generally better to use let and const instead of var because of their nature in scoping and hoisting which can lead to some bugs if you are not familiar with its nature. Also how you declare your functions changes the hoisting, arrow functions will not be hoisted where function() will be.

Let and const are block scoped and var is function scoped, var will also be hoisted which means that it bubbles up to the top of the file. Block scoped means that you can only handle the variables inside blocks for example if else where function scopes means that you can reach variables everywhere inside a function.

const checkScope = () => {
  console.log(varInsideBlock) // will print undefined 
  cause of hoisting this becomes the declaration var varInside; 

  if(1 === 1) {
    var varInsideBlock = "function scoped";
    let letOrConstInsideBlock = "block scoped";
  };

  console.log(varInsideBlock) // will print 
  console.log(letOrConstInsideBlock ) // will produce ReferenceError
};

checkScope();

Array methods

Use array methods instead of for loops when you are working with arrays or NodeLists. For loops are better if you are working with numbers etc.

buttons.forEach(button => {
  button.addEventListener("click", function() {
    button.classList.toggle("selected");
    result = button.innerHTML;
    span.innerHTML = result;
  })
  button.addEventListener("blur", function() {
    button.classList.remove("selected")
  })
});`
