等等
下面討論的標(biāo)簽是 HTML5 版本中新引入的標(biāo)簽。它們是不同類型的標(biāo)簽，都可以分類。
1.結(jié)構(gòu)標(biāo)簽
以下是結(jié)構(gòu)標(biāo)簽的類型及示例：
a。文章： 這是一個(gè)最常用的標(biāo)簽，類似于 head 標(biāo)簽。主要用于表單、博客、新聞報(bào)道等示例。
代碼：
<html>
<article> <h3>The first one </h3></article>
<body>
<h2>Welcome Back</h22>
</body>
</html>
輸出：
b。旁白： 類似于我們普通標(biāo)簽的東西，它將內(nèi)容與周圍的內(nèi)容相關(guān)聯(lián)，就像文章中的側(cè)邊欄。而且這個(gè)標(biāo)簽只有在使用8以上的IE版本時(shí)才有意義。
c.詳細(xì)信息：該標(biāo)簽用于向用戶提供一些附加數(shù)據(jù)。這可以是一個(gè)可以隱藏或顯示細(xì)節(jié)的交互平臺(tái)。我們可以在summary標(biāo)簽下看到這個(gè)tab的用法。
d。標(biāo)題：此標(biāo)簽與標(biāo)題部分相關(guān)，包含標(biāo)題信息。它必須有開始標(biāo)簽和結(jié)束標(biāo)簽。
代碼：
<html>
<header>
<h1>Happy Hours</h1>
<nav>
<p><a href="#">Morning</a> | <a href="#">Afternoon</a> | <a href="#">Evening</a></p>
</nav>
</header>
</html>
輸出：
e。 hgroup: 該標(biāo)簽用于描述一組標(biāo)頭。讓我們看一下例子。
代碼：
<html>
<body>
<hgroup>
<h1>Let’s check size of this h1 </h1>
<h2> Let’s check size of this h2 </h2>
<h3> Let’s check size of this h3</h3>
<h4> Let’s check size of this h4</h4>
<h5> Let’s check size of this h5</h5>
</hgroup>
</body>
</html>
輸出：
f。頁腳： 這個(gè)標(biāo)簽就是那個(gè)，它被放置在頁面的末尾。它涉及版權(quán)、歷史相關(guān)信息或數(shù)據(jù)等內(nèi)容。讓我們看下面的一個(gè)小例子。
代碼：
<html>
<body>
<footer>
<nav>
<p><a href="#">Copy Rights</a> | <a href="#">Come back soon</a></p>
</nav>
<p>Please subsribe for more learning content</p>
</footer>
</body>
</html>
輸出：
g。 nav: 此標(biāo)簽用于提供所有鏈接的一部分進(jìn)行導(dǎo)航。
代碼：
<html>
<body>
<nav>
<ul>
<li><a href="https://www.educba.com/">EDUCBA Home</a></li>
<li><a href="https://www.educba.com/about-us/">About EDUCBA</a></li>
<li><a href="https://www.educba.com/courses/">Courses in EDUCBA</a></li>
</ul>
</nav>
</body>
</html>
輸出：
在練習(xí)時(shí)編寫代碼后，請(qǐng)單擊鏈接進(jìn)行檢查。
h。部分： 正如名稱所示，該標(biāo)簽定義了代碼的正文、頁眉、頁腳等部分。這里，開始標(biāo)簽和結(jié)束標(biāo)簽都是必需的。讓我們看下面的一個(gè)小例子：
代碼：
<html>
<section>
<h1> Welcome </h1>
<h4> See you soon </h4>
<p>Thank You.</p>
</section>
</html>
輸出：
我。摘要：此標(biāo)簽與詳細(xì)信息選項(xiàng)卡并行使用。在詳細(xì)信息標(biāo)簽下，我們有一個(gè)摘要標(biāo)簽來總結(jié)概念。以下示例：
代碼：
<html>
<body>
<details>
<summary>How is this Summary tag defined?</summary>
<p>By clicking the arrow beside the Summary question I got displayed</p>
</details>
<p> The data after the display tag is displayed like this.</p>
</body>
</html>
輸出：
現(xiàn)在展開摘要標(biāo)簽數(shù)據(jù)，我們得到以下內(nèi)容。
2.表單標(biāo)簽
以下是不同類型的表單標(biāo)簽，并舉例說明：
a。 Datalist： 此標(biāo)簽的使用方式類似于下拉列表，其中有預(yù)定義的值供用戶選擇。讓我們看一下下面的小例子：
代碼：
<html>
<body>
<p>Enter your favorite browser name:</p>
<input type="text" list="browsers">
<datalist id="browsers">
<option value="Firefox">
<option value="Chrome">
<option value="Internet Explorer">
<option value="Opera">
<option value="Safari">
</datalist>
</body>
</html>
輸出：
鼠標(biāo)懸停時(shí)會(huì)彈出下拉菜單。
b. Keygen: This is for the encryption. It is for generating an encrypted key for passing the data in an encrypted format. Only the start tag is enough/required for this element, and the end tag is not mandatory.
c. Meter: This tag would give us the measurement of the data which is present in a given range.
Code:
<html>
<body>
<meter value="25" min="0" max="100">25 out of 100</meter><p> This is 25 out of 100 </p><br>
<meter value="0.7">70%</meter><p> This is the range for 70%</p>
</body>
</html>
Output:
Below are the types of formatting tag with examples:
a. BDI: This is Bi-directional isolation. As the name already suggests, this tag can be used to isolate a part of the text and give it different styles from that of other text.
b. Mark: This tag can help us highlight a specific text.
Code:
<html>
<body>
<p>This is how you can <mark>mark or highlight</mark> a text.</p>
</body>
</html>
Output:
c. Output: As the name already shows us, it gives the result of any calculation.
Code:
<html>
<body>
<form oninput="sum.value=parseInt(x.value)+parseInt(y.value)">
<input type="number" id="x”> +
<input type="number" id="y" value="350"> =
<output name="sum" for="x y"></output>
</form>
</body>
</html>
Output:
Make sure that you notice the form attribute of oninput. Once you input the attribute ‘x’ value, then the output gets displayed.
d. Progress: This tag gives us the progress of a particular task.
Code:
<html>
<body>
<progress value="80" max="100"></progress><p> This progress bar is 80% completed</p>
</body>
</html>
Output:
e. Rp: This is used when the ruby tags are not supported.
f. Rt: It is used with the tag ruby. Mostly this is used in pronunciation in both Japanese and Chinese languages.
g. Ruby: This tag is used with the rt and rp tags where the annotations with respect to the two languages, Chinese and Japanese, are pronounced.
h. Wbr: This tag is for the word break. It is mainly used to check how a word breaks when the window size is resized.
4. Embedded Content Tags
Here are the types of embedded content tag explained below with examples:
a. Audio: As the name already suggests, this tag would help us to incorporate audio files in the HTML document.
b. Canvas: Defines a place on the web page where graphics or shapes, or graphs are present or can be defined. Here is an example.
Code:
<html>
<body>
<canvas id="run" ></canvas>
<script type="text/javascript">
window.onload = function(){
var can = document.getElementById("run");
var context = can.getContext("2d");
context.moveTo(30, 60);
context.lineTo(150, 30);
context.stroke();
};
</script>
</body>
</html>
Output:
c. Dialog: This tag gives us a default box, especially if we wanted to have data in a box.
Code:
<html>
<body>
<p> Trying dialog here <dialog open>How does dialog box come up?</dialog> </p>
</body>
</html>
Output:
d. Embed: This tag can be used for getting in any external file to the HTML file. We can have only the start tag, and the end tag is not mandatory here. There are different attributes that can be used with this tag, namely, width, height, src, and type.
e. Figure and Figcaption: This, as already in its name, can incorporate the images and can give a caption to that image.
f. Source:?This tag can implement multiple audio and video files by providing the location of the files using this source tag.
g. Time: This tag, as the name already notifies, is a tag for displaying the time. And note that this tag is not functional in the cases of internet explorer version 8 and below.
h. Video: With the name of the tag, we can obviously get to know where this tag is used. For specifying the video files, we have this tag. Inside this Audio/Video tags, we define the source tags in specifying the files and their locations.
Here are some input elements which we are using in HTML5 tags:
1. Email: This is one of the input elements in HTML5. This element takes in only email addresses as the input.
2. Number: This input element only accepts the number.
3. Range: As the name already explains, this tag contains a range of numbers.
4. URL: This input tag accepts the input field for the URL address. In this input type, we can only enter the URL.
5. Placeholder: This is one of the attributes for the input type as text or text area or any number. This place holder value shows the value to be given as the input.
Code:
<html>
<body>
Enter Date of birth : <input type = "text" name = "dob"
placeholder = "dd/mm/yyyy"/>
</body>
</html>
Output:
6. Autofocus: This attribute automatically focuses on a particular field where this element has been declared inside the input tag. This attribute is supported only by the latest versions of Chrome, Safari, and Mozilla only. The syntax is like this:
<input type = “textarea” name=”focus” autofocus/>
Tag <dd>: This tag represents a description of a definition.
Tag <del>: This tag deletes a specified text.
Tag <marquee>: This tag helps to display data in a scrolling manner.
<html>
<body>
<marquee> This texxt is in a scrolling manner </marquee>
</body>
</html>
Output:
7. : This is one of the basic tags that would help the browser understand the HTML version in which the program is being written. The declaration of this tag is to be written before the HTML tag.
8. : This Meta tag describes the description of the HTML document. It contains the author’s name, date, and modifications, etc.
In this HTML5, we even have an opportunity to get the GeoLocation of a device. There are different methods that can be helpful in making this location tagging easy. There are also different fonts and colors available in HTML5. Below are the few tags that are removed from the HTML usage from this HTML5 version.
Acronym, Applet, big, dir, font, frameset, center, tt (TeleType text), basefont, center, strike, frame, u (underlined text), isindex, noframes, etc. Few attributes that are removed are below:
Align, bgcolor, cellpadding, cellspacing, border, link, shape, charset, archive, codebase, scope, alink, vlink, link, background, border, clear, scrolling, size, width, etc.
