Can CSS Selectors Target Input Values?

Targeting Input Values with CSS Selectors

Query: Can CSS selectors be employed to target inputs based on their specific values? For example, how can an input with the value "United States" be isolated?

Answer:

Conventional CSS Approach:

Yes, it is possible. CSS attribute selectors enable targeting inputs based on their values. The following rule targets the input with the value "United States":

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

Challenges with Dynamic Values:

The above approach targets the HTML node's attribute value. However, if the value changes dynamically, the CSS rule won't apply.

JavaScript Intervention:

To dynamically target input values, JavaScript can be utilized as a workaround. One method is shown in this jsFiddle:

<code class="html"><input type="text" id="country" value="United States"></code>

<code class="javascript">var countryInput = document.getElementById('country');
if (countryInput.value === 'United States') {
  countryInput.style.color = '#F90';
}</code>

This script checks the value of the input and applies the style if it matches the desired value.

In Conclusion:

CSS selectors provide a convenient way to target input values. For static values, attribute selectors suffice. However, for dynamic values, JavaScript solutions become necessary to ensure CSS rules are applied correctly.
