html - Can I apply a CSS style to an element name?

You can use the attribute selector,

input[name="goButton"] {
  background: red;
}

<input name="goButton">

Text Input Example

input[type=text] {
  width: 150px;
}

input[name=myname] {
  width: 100px;
}

<input type="text">
<br>
<input type="text" name="myname">

You can use attribute selectors but they won't work in IE6 like meder said, there are javascript workarounds to that tho. Check Selectivizr

More detailed into on attribute selectors: http://www.css3.info/preview/attribute-selectors/

/* turns all input fields that have a name that starts with "go" red */
input[name^="go"] { color: red }

For future googlers, FYI, the method in the answer by @meder , can be used with any element that has a name attribute, so lets say theres an <iframe> with the name xyz then you can use the rule as belows.

iframe[name=xyz] {    
    display: none;
}   

The name attribute can be used on the following elements:

• <button>
• <fieldset>
• <form>
• <iframe>
• <input>
• <keygen>
• <map>
• <meta>
• <object>
• <output>
• <param>
• <select>
• <textarea>

If i understand your question right then,

Yes you can set style of individual element if its id or name is available,

e.g.

if id available then u can get control over the element like,

<input type="submit" value="Go" name="goButton">

var v_obj = document.getElementsById('goButton');

v_obj.setAttribute('style','color:red;background:none');

else if name is available then u can get control over the element like,

<input type="submit" value="Go" name="goButton">

var v_obj = document.getElementsByName('goButton');

v_obj.setAttribute('style','color:red;background:none');

Using [name=elementName]{} without tag before will work too. It will affect all elements with this name.

For example:

[name=test] {
  width: 100px;
}

<input type=text name=test>
<div name=test></div>

This is the perfect job for the query selector...

var Set1=document.querySelectorAll('input[type=button]');  // by type

var Set2=document.querySelectorAll('input[name=goButton]'); // by name

var Set3=document.querySelectorAll('input[value=Go]'); // by value

You can then loop through these collections to operate on elements found.

have you explored the possibility of using jQuery? It has a very reach selector model (similar in syntax to CSS) and even if your elements don't have IDs, you should be able to select them using parent --> child --> grandchild relationship. Once you have them selected, there's a very simple method call (I forget the exact name) that allows you to apply CSS style to the element(s).

It should be simple to use and as a bonus, you'll most likely be very cross-platform compatible.
