html hidden tags

HTML has many different tags that can be used to define the structure and content of web pages. Some tags are directly displayed to users on the page, while some tags are hidden and only play a role in the code. This article will introduce hidden tags in HTML, including comment tags, meta tags, style tags, script tags, input tags, etc.

1. Comment tag

In HTML, comment tags are used to add comments in the code without having any impact on the browser's rendering results. The syntax format of the comment tag is as follows:

In the comment tag, we can add anything we want to comment so that we or Other editors understand and interpret the code when they later read it. The role of comment tags is not only to improve the readability of the code, but also to temporarily hide certain content when needed.

2. meta tag

meta tag is a tag used to define metadata in the header of a web page. Metadata can include the page’s title, keywords, description, author and other information. The syntax format of the meta tag is as follows:

Among them, the name attribute specifies the name of the metadata, and the content attribute specifies The value of the metadata. Through meta tags, we can allow search engines to better understand and index the content of our pages, thus improving the SEO effect of the website.

3. style tag

The style tag is used to define style information in web pages, such as text color, background color, font size, etc. Using the style tag can help us manage the style of web pages more conveniently and avoid repeatedly defining styles multiple times in HTML tags. The syntax format of the style tag is as follows:

The type attribute specifies the style type It is text/css, and the style information includes a series of CSS codes. Using style sheets can reuse page styles and make the page more concise and clear.

4. script tag

script tag is used to define scripts in web pages, such as JavaScript scripts. Through script tags, we can implement various functions in the page, such as verifying forms, dynamically loading data, calling API interfaces, etc. The syntax format of the script tag is as follows:

The type attribute specifies the script type For text/javascript, the script information is the JavaScript code we need to execute. Using JavaScript can increase the interactivity of web pages, making users' operations on the page more free and convenient.

5. input tag

The input tag is a tag used to submit data to the server through a form. However, in the page, we usually hide the input tag to store some data or perform some operations. The type attribute of the input tag can be set to hidden, so that the tag can be hidden and not displayed on the page. The syntax format of the input tag is as follows:

Among them, the name attribute specifies the parameter name, and value Properties specify the value of the parameter. Through hidden input tags, we can pass some implicit data in the page, such as cookie information, page jump address, etc., to provide our website with a more convenient user experience and functions.

To write high-quality HTML code, we need to be proficient in these hidden tags. They can not only improve our development efficiency, but also allow us to better understand and manage the structure and content of web pages. I hope readers can bring better experience and results to their website development work through learning.
