Can CSS Attribute Selectors Target Dynamic Input Values?

CSS Attribute Selectors for Dynamic Input Targeting

Question: Can you leverage CSS selectors to target inputs based on their specific values? For instance, how would you target an input with the value "United States"?

Answer:

Original Solution: Static Values Only

Yes, it's possible using CSS attribute selectors. However, they have a limitation:

<code class="css">input[value="United States"] { color: #F90; }</code>

This selector matches inputs with the exact value "United States". If the value changes dynamically, the styling won't be applied.

Solution for Dynamic Values

As noted in npup's answer, CSS attribute selectors cannot target attributes based on their actual values. To address this challenge:

• JavaScript Workaround: Create a JavaScript function that checks the input values and applies styling dynamically. See the provided JSFiddle for an example.

Limitations of Dynamic Value Targeting

While JavaScript provides a solution, it's important to note that it's a potential performance bottleneck. Additionally, it's not supported in all browsers.

Use Cases

Dynamic value targeting can be useful in specific scenarios, such as:

• Highlighting invalid input with particular values.
• Restricting user interactions to certain input values.
