TIL, CSS shadow and FrontEnd interview questions

Hello guys,

This week I have a lot of assignments and an interview, so I spent most of my time preparing for them. So please wish me luck tomorrow to do my best in the interview.

First of all, I read a fantastic article about CSS shadow

They're Shadow Hover Effect, A Shadow Of A Shadow and The Textual Shadow

Shadow hover effect

<div class="circle"></div>

.circle{
     width: 250px;
     height: 250px;
     background: green;
     border-radius: 50%;
     box-shadow: inset 250px 250px 0 red;
}

.circle:hover{
    box-shadow: none;
}

Checkout the result

and this

A Shadow Of A Shadow

The Textual Shadow

text-shadow: h-shadow v-shadow blur-radius color|none|initial|inherit;

h1 {
  text-shadow: 0 0 3px #FF0000, 0 0 5px #0000FF;
}

<h1>Text-shadow with red and blue neon glow</h1>

Here's the result

Secondly, some interview questions that I initially didn't know how to answer
