Answer 1

In .css

.holder:before {
    content: attr(placeholder);
    color: lightgray;
    display: block;
    position:absolute;    
    font-family: "Campton", sans-serif;
}

in js.

clickedOnInput:boolean = false;
charactorCount:number = 0;
let charCount = document.getElementsByClassName('edit-box')[0];

if(charCount){
this.charactorCount = charCount.innerText.length;
}

if(charactorCount > 0 && clickedOnInput){
document.getElementById("MyConteditableElement").classList.add('holder');
}

if(charactorCount == 0 && !clickedOnInput){
document.getElementById("MyConteditableElement").classList.remove('holder');
}

getContent(innerText){
  this.clickedOnInput = false;
}

In .html

this solution worked for me in angular project
