HTML Guide - issues tagged as name

Attribute “name” not allowed on element “meta” at this point.

meta
name

A <meta> tag has been found that is either malformed, or in a bad place within the document. Check its attributes and context.

For example, the following HTML contains a valid <meta> tag that is raising an issue because of bad context, caused by an <img> tag that shouldn’t be there:

<!DOCTYPE html>
<html lang="">
  <head>
    <title>Test</title>
    <img src="photo.jpg" alt="A smiling cat" />
    <meta name="description" content="Description of this page" />
  </head>
  <body>
    <p>Some content</p>
  </body>
</html>

If we fix that document and move the <img> tag within the body, the issue raised about <meta> disappears because it’s now in a valid context:

<!DOCTYPE html>
<html lang="">
  <head>
    <title>Test</title>
    <meta name="description" content="Description of this page" />
  </head>
  <body>
    <p>Some content</p>
    <img src="photo.jpg" alt="A smiling cat" />
  </body>
</html>

Bad value “” for attribute “name” on element “form”: Must not be empty.

name
form

An empty value for the name attribute on the form element is invalid and should be removed or replaced with a valid non-empty string.

The name attribute on a form element provides a way to reference forms via scripts and images, and it must not be empty. According to the HTML standard, if the name attribute is present, it must have a non-empty value. An empty string is considered invalid and will trigger HTML validator errors.

Invalid example:

<form name="">
  <!-- form elements here -->
</form>

How to fix:

Remove the empty name attribute if you don’t need it.
Replace the empty value with a meaningful, unique name if you require it for scripting or identification.

Valid examples:

<form>
  <!-- form elements here -->
</form>

<form name="registrationForm">
  <!-- form elements here -->
</form>

Avoid using empty attribute values, as they do not provide any benefit and result in validation errors.

Bad value “” for attribute “name” on element “input”: Must not be empty.

Bad value X for attribute “name” on element “iframe”: Browsing context name started with the underscore.

The value of the name attribute on an <iframe> should not start with an underscore (_).

Browsing context names that begin with an underscore are reserved keywords in HTML, like _blank, _self, _parent, and _top. Using these reserved names or any custom name starting with an underscore for the name attribute of an <iframe> can lead to unexpected behavior and is considered invalid HTML.

Here’s how to fix the issue:

Problematic Code

<iframe src="https://example.com" name="_example"></iframe>

Solution

To resolve this issue, you should use a valid value for the name attribute that does not start with an underscore.

Corrected Code

<iframe src="https://example.com" name="example"></iframe>

Steps:

Identify the iframe element with the invalid name attribute value that starts with an underscore.
Replace the name value with a valid identifier that does not start with _. Use letters, numbers, hyphens (-), and underscores (_) (but not at the beginning).

Element “meta” is missing one or more of the following attributes: “charset”, “content”, “http-equiv”, “itemprop”, “name”, “property”.

There’s an incomplete or incorrectly formed <meta> tag. The <meta> tag in HTML is used to provide metadata about the HTML document. This metadata is typically specified using attributes like charset, content, http-equiv, itemprop, name, and property.

To fix this issue, you need to ensure that your <meta> tags include at least one of these attributes. Here are some examples of properly formed <meta> tags with each of these attributes:

Using the charset attribute:
```
<meta charset="UTF-8">
```
This specifies the character encoding for the HTML document, which is crucial for displaying text correctly in different languages.
Using the content and name attributes:
```
<meta name="description" content="A brief description of the webpage content.">
```
This provides a description of the webpage content, which can be used by search engines.
Using the http-equiv and content attributes:
```
<meta http-equiv="refresh" content="30">
```
This specifies information to be passed to the browser, such as refreshing the page every 30 seconds.
Using the property and content attributes:
```
<meta property="og:title" content="Your Webpage Title">
```
This is used for Open Graph meta tags, which improve the appearance of shared content on social media platforms.

Correct Usage Example

Here’s an example of an HTML document with a properly formed set of <meta> tags:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta name="description" content="A brief description of the webpage content.">
    <meta http-equiv="refresh" content="30">
    <meta property="og:title" content="Your Webpage Title">
    <title>Document</title>
</head>
<body>
    <!-- Page content goes here -->
</body>
</html>

The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.

In the days before HTML5, named anchors were used as a way to provide a link to a specific section of a document, for example:

<h2>
  <a name="section-5">Section 5</a>
</h2>

Now in HTML5, the name attribute is obsolete for <a> tags, and instead, you can use the id attribute of any element (not just <a>) as a way to navigate directly to it, for example:

<h2 id="section-5">Section 5</h2>

The “name” attribute on the “img” element is obsolete. Use the “id” attribute instead.

The warning regarding the use of the name attribute on the img element arises because the name attribute is considered obsolete in modern HTML. Historically, name was used to identify form controls and some other elements, but now it’s replaced by more standardized attributes like id.

To resolve this issue, replace the name attribute with the id attribute. The id attribute provides a unique identifier for the element within the document, which can be utilized for styling, scripting, or linking using fragment identifiers.

Here is an example of how to make this change:

HTML with obsolete name attribute:

<img src="example.jpg" name="myImage" alt="Descriptive text">

Updated HTML using the id attribute:

<img src="example.jpg" id="myImage" alt="Descriptive text">

In this modification:

The name="myImage" is replaced with id="myImage".
The remaining attributes like src and alt are retained for specifying the image source and providing alternative text, respectively.

The id attribute should be unique within the document, which ensures that JavaScript or CSS can target the element efficiently.

The “name” attribute on the “option” element is obsolete. Use the “id” attribute instead.

The <option> element no longer accepts a name attribute, which is now obsolete.

Example:

<select id="pet-select">
    <option value="">--Please choose an option--</option>
    <option value="dog">Dog</option>
    <option value="cat">Cat</option>
    <option value="hamster">Hamster</option>
</select>
