CSS Flexbox - Use display: flex to Position Two Boxes

CSS Flexbox - Use display: flex to Position Two Boxes

Placing the CSS property display: flex; on an element allows you to use other flex properties to build a responsive page.

imagine you have to divs that want to display side by side in one container
first we should give display: flex; on that container and give 50% for width and height for both contained boxes as follow:

<style>
  #box-container {
    height: 500px;
    display:flex;
  }
  
  #box-1 {
    background-color: dodgerblue;
    width: 50%;
    height: 50%;
    
  }

  #box-2 {
    background-color: orangered;
    width: 50%;
    height: 50%;
    
  }
</style>
<div id="box-container">
  <div id="box-1"></div>
  <div id="box-2"></div>
</div>

see the result now for that code

as we see the two boxes are displayed as one row as the flex source

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...
