Uncommon HTML tags nowadays, web development engineers usually use more than one language to learn and work. Therefore, it is hard to understand all aspects of a language. It is also quite difficult to master a language. For example, some of the uncommon but potentially useful keywords in a language are used.

Although we may not know these very rare HTML tags or do not fully use them in the past, it is not too late to make up for it, it is not too late to understand and use these unused labels correctly in future development.

Here I have provided 10 HTML tags that are the least common and often misused. Although it may not be as common as other HTML tags, they are still quite useful in some special scenarios.

1. <cite>

I believe everyone is familiar with <BLOCKQUOTE>, but you know that <BLOCKQUOTE> is actually a younger brother called <cite>? <Cite> A piece of text can be defined in an element as a reference. Generally, the browser sets the text under the <cite> label to italic, but this may change according to CSS.

<Cite> tags are useful when referencing book directories and other website addresses. Here is an example of how to use the <cite> label in a piece of text:

James's breakthrough MonographZhang San's AutobiographyIt brings a new atmosphere to the network.

2. <optgroup>

The <optiongroup> label is useful when you want to add some definitions to the options of different types of groups in a drop-down box. For example, if you want to group movies by time, you can write the code as follows:

Example:

Showtimes 
 Twister Napoleon DynamiteWhat about Bob? Be Kind Rewind Stranger than fiction3. <acronym>

<Acronym> labels are generally used to add definitions or more detailed explanations for a sentence (phrase. When you move your cursor over the text with the <acronym> label added, the added comments or definitions are displayed below the text. For example:

Example:

4. <address>

<Address> A tag is a rare one, but it does not mean it is useless. <Address> allows you to mark addresses in HTML based on semantics. This easy-to-use label will also mark its internal data in italics. However, this style can be easily modified through CSS.

Example:

5. <ins> and <del>

If you want to display the document editing style by TAG, <ins> and <del> can be used. Just like their names, <ins> uses an underscore to highlight the content added to the document, while <del> deletes the text from the document.

Example: What should we do without a donkey?Coming soon Live?

6. <label>

When marking a document, table elements are easily forgotten. One of the most easy-to-Forget elements in a table is afraid of a number <label> label. But for a <label> label, it not only can easily represent a piece of text, but also can use the for attribute to specify which element the label is used. These <label> are not only easy to define styles, but they also allow you to design the image button of the label text to be clicked by the user.

7. <fieldset>

<Fieldset> is a very useful label that groups related elements in a form by logic. Once these elements are put together through the <fieldset> label, and by binding the <label> label and fieldset, the title can be defined for the group.
