DHTML stands for Dynamic Hypertext MarkupLanguage i.e. Dynamic HTML. DHTML and HTML do not compete with each other, but it can be said that DHTML is the extended version of HTML along with using different web technologies. The HTML helps build static web pages, whereas DHTML allows for designing dynamic web pages with more interactivity. It allows designing an intuitive, dynamic user interface along with animations. It is not a specific technology or a standard, but it is a concept where multiple other technologies are used together to achieve a result. These different technologies used in DHTML are known as components.
Why do we need DHTML?
Microsoft first introduced the application of DHTML in 1997 with the release of Internet Explorer version 4. Without DHTML, there used to be the use of only static web page. There are some incapabilities or disadvantages while using static web pages. There is no interactivity with static pages for the user. The page needs to be refreshed every time user wants some change. No dynamic actions can be taken on a web page without reloading it. The DHTML, however, provides the capability to achieve all of this.
The DHTML allows changing the web components dynamically on the client-side without reloading the web page. It provides a user with the flexibility to interact and change the values directly. DHTML allows us to change or alter the values and functions to perform differently according to the users. DHTML is a very broad concept; it will load the web page depending upon different users, load occurrence, or the values provided by users.
DHTML Components
As said in the introduction, DHTML uses different web technologies together, and these are known as DHTML components. DHTML uses a combination of the below components to make websites interactive and achieve animations in a web site.
- HTML- Static Markup Language
- JavaScript- Scripting Language
- CSS- Style sheet Language
- DOM- Document Object Model
1. HTML
HTML is a client-side markup language that is used to design static web pages. HTML is the core component of DHTML. It defines the web page components to be displayed on a web page. HTML defines the structuring of components by using different elements and tags. HTML, however, allows to design only static web page; the user cannot change the values of elements dynamically at the client-side. But still, HTML is the basic component that is required to build a web site.
2. JavaScript
JavaScript is a client-side scripting language that is used to make static web pages dynamic. JavaScript allows changing the variable values, altering functions, and performing various activities as per user needs. JavaScript allows taking decisions on the client-side before sending them to the server, thus allowing a user to save time. We can program the behavior of the web page by using JavaScript. JavaScript allows the implementation of complex functionality and features on a web page. It allows us to update content dynamically, make some animations, and many more things.
3. CSS
Just as HTML is used to build web pages, CSS is used to design them and implement styles. CSS stands for Cascading Style Sheet, which is language to design web pages. CSS allows designing the layout and other styles that define how elements will be displayed on a web page. The same CSS file can be used on multiple web pages, which can save the amount of work and time. CSS supports JavaScript and DOM. By using this combination, we can change the styling and layout of the web page dynamically.
4. DOM
DOM stands for Document Object Model. It defines the logical structure of elements on a web page, and it provides a standard to access the elements and manipulate them. The DOM represents the main objects and elements on a web page and how they are related to each other. Using DOM and JavaScript, and CSS, we can change the style, structure, and content of web pages dynamically. DOM allows us to access the elements directly and precisely.
DHTML の機能

メリットとデメリット
以下に長所と短所を示します
メリット
以下に利点を示します:
- DHTML を使用すると、静的な Web ページと比較して、よりインタラクティブな動的 Web ページを作成できます。
- Flash や Shockwave などの他のマルチメディア ソフトウェアと比較して、DHTML はファイル サイズがコンパクトで、クライアント マシンにすばやくダウンロードできるため、帯域幅と時間を節約できます。
- Web ページを再読み込みしたり更新したりせずに、クライアント マシンでコンテンツを変更できます。
- 今日の時点でほぼすべてのブラウザでサポートされており、追加のソフトウェアを実行する必要はありません。
- 効率的で、ファイルの保守が容易です。これにより、Web デザイナーはより柔軟に対応できるようになります。
デメリット
以下に欠点を示します:
- DHTML は複数のテクノロジーを組み合わせるため、Web デザイナーはそれらのテクノロジー全体にコマンドを必要とします。
- Web ページがさまざまなブラウザーで適切に動作するように注意する必要があります。
- DHTML を使用する場合、ブラウザの互換性チェックは必須です。 DHTML がすべてのプラットフォームで同じように動作するという保証はありません。
結論
DHTML は、HTML、CSS、JavaScript、DOM などの複数のテクノロジーを組み合わせて最終結果を得ることができる Web デザインの概念です。 DHTML を使用すると、さまざまなスタイルで動的な Web ページを構築できます。 Web ページ上でアニメーションを作成することもできます。

HTML, CSS and JavaScript are the three pillars of web development. 1. HTML defines the web page structure and uses tags such as, etc. 2. CSS controls the web page style, using selectors and attributes such as color, font-size, etc. 3. JavaScript realizes dynamic effects and interaction, through event monitoring and DOM operations.

HTML defines the web structure, CSS is responsible for style and layout, and JavaScript gives dynamic interaction. The three perform their duties in web development and jointly build a colorful website.
