CSS Grid: Align an Item Horizontally using justify-self

In CSS Grid, the content of each item is located in a box which is referred to as a cell.
You can align the content's position within its cell horizontally using the justify-self property on a grid item.
By default, this property has a value of stretch, which will make the content fill the whole width of the cell.
This CSS Grid property accepts other values as well: 

stretch: default value that will fill to the cell,
start: aligns the content at the left of the cell,
center: aligns the content in the center of the cell,
end: aligns the content at the right of the cell.

1. div .item2 default with justify-self:stretch; or without it

ES6 : 5 Prevent Object Mutation

As seen in the previous post declaration alone doesn't really protect your data from mutation. To ensure your data doesn't change, JavaScript provides a function Object.freeze() to prevent data mutation. Once the object is frozen, you can no longer add, update, or delete properties from it. Any attempt at changing the object will be rejected without an error. let obj = { name:"FreeCodeCamp" review:"Awesome" }; Object.freeze(obj); obj.review = "bad"; //will be ignored. Mutation not allowed obj.newProp = "Test"; // will be ignored. Mutation not allowed console.log(obj); // { name: "FreeCodeCamp", review:"Awesome"}

ES6: 1 Explore Differences Between the var and let Keywords

One of the biggest problems with declaring variables with the var keyword is that you can overwrite variable declarations without an error. var camper = 'James'; var camper = 'David'; console.log(camper); // logs 'David' As you can see in the code above, the camper variable is originally declared as James and then overridden to be David . In a small application, you might not run into this type of problem, but when your code becomes larger, you might accidentally overwrite a variable that you did not intend to overwrite. Because this behavior does not throw an error, searching and fixing bugs becomes more difficult. A new keyword called let was introduced in ES6 to solve this potential issue with the var keyword. If you were to replace var with let in the variable declarations of the code above, the result would be an error. let camper = 'James'; let camper = 'David'; // throws an error This error can be seen...

CSS Grid: Reduce Repetition Using the repeat Function

 When we used grid-template-columns and grid-template-rows to define the structure of a grid, you entered a value for each row or column you created. Lets say you want a grid with 100 rows of the same height. It isn't very practical to insert 100 values individually. Fortunately, there's a better way - by using the repeat function to specify the number of times you want your column or row to be repeated, followed by a comma and the value you want to repeat. Here's an example that would create the 100 row grid, each row at 50px tall. grid-template-rows: repeat(100, 50px); You can also repeat multiple values with the repeat function, and insert the function amongst other values when defining a grid structure. Here's what I mean: grid-template-columns: repeat(2, 1fr 50px) 20px;  this will be translated to :            grid-template-columns:1fr 50px 1fr 50px  20px;   1fr 50px is repeated t...
