How to use Angular HTML binding

In this article let’s understand Angular HTML binding and how to use angular html binding and how to display in angular.

In Angular, we use HTML binding to dynamically render and display HTML content in your templates. It allows you to bind HTML markup stored in variables or properties directly to the HTML template, enabling dynamic rendering of content.

Angular provides different mechanisms for HTML binding depending on the source of the HTML content and the desired behaviour. Let’s explore a few of these mechanisms:

Interpolation ({{ }}):

Interpolation is the simplest way to bind HTML content within double curly braces. It allows you to bind the value of a variable or expression directly into the HTML template.

<div>{{ htmlContent }}</div>

In this example, the value of the htmlContent variable will be dynamically rendered within the <div> element. Note that Angular automatically escapes any potentially unsafe HTML content by default to prevent XSS attacks. If you want to bind raw HTML content, you can use the innerHTML property or a specific directive, as explained next.

[innerHTML] property binding

To bind HTML content as raw, unescaped HTML, you can use the [innerHTML] property binding. This approach allows you to assign a property containing HTML markup directly to an element’s innerHTML property.

<div [innerHTML]="htmlContent"></div>

In this case, the value of the htmlContent property is treated as raw HTML and rendered as-is within the <div> element.


When dealing with potentially unsafe HTML content, such as user-generated content, it’s important to sanitize and mark it as safe to avoid security vulnerabilities. Angular provides the DomSanitizer service to help you sanitize and bind HTML content safely.

import { Component, OnInit } from '@angular/core';
import { DomSanitizer, SafeHtml } from '@angular/platform-browser';

  selector: 'app-my-component',
  template: `
    <div [innerHTML]="getSafeHtml()"></div>
export class MyComponent implements OnInit {
  unsafeHtml: string = '<p>Unsafe HTML content</p>';
  safeHtml: SafeHtml;

  constructor(private sanitizer: DomSanitizer) {}

  ngOnInit() {
    this.safeHtml = this.sanitizer.bypassSecurityTrustHtml(this.unsafeHtml);

  getSafeHtml(): SafeHtml {
    return this.safeHtml;

In this example, the DomSanitizer service is used to sanitize and mark the unsafeHtml as safe before binding it to the [innerHTML] property. We can reduce security risk by sanitising using this approach.

This way we can properly sanitize content to prevent security vulnerabilities like Cross-Site Scripting (XSS) attacks.

These are the common approaches to HTML binding in Angular. Choose the appropriate method based on your use case and the level of trustworthiness of the HTML content you’re binding.
