Center an Element Horizontally "Using the margin Property"

 

 Applied Visual Design - Center an Element Horizontally Using the margin Property

Another positioning technique is to center a block element horizontally. One way to do this is to set its margin to a value of auto.
This method works for images, too. Images are inline elements by default, but can be changed to block elements when you set the display property to block.
Center the div on the page by adding a margin property with a value of auto.

<style>
  div {
    background-color: blue;
    height: 100px;
    width: 100px;
    margin:auto;


 }


 


 </style>









<div></div>

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...
