Change Input Placeholder Color Darker

Change input placeholder color darker

I've found you need to override opacity.

::-webkit-input-placeholder { /* WebKit browsers */
    color:    red;
     opacity: 1 !important;
}

Change a HTML5 input's placeholder color with CSS

Implementation

There are three different implementations: pseudo-elements, pseudo-classes, and nothing.

• WebKit, Blink (Safari, Google Chrome, Opera 15+) and Microsoft Edge are using a pseudo-element: ::-webkit-input-placeholder. ^[Ref]
• Mozilla Firefox 4 to 18 is using a pseudo-class: :-moz-placeholder (one colon). ^[Ref]
• Mozilla Firefox 19+ is using a pseudo-element: ::-moz-placeholder, but the old selector will still work for a while. ^[Ref]
• Internet Explorer 10 and 11 are using a pseudo-class: :-ms-input-placeholder. ^[Ref]
• April 2017: Most modern browsers support the simple pseudo-element ::placeholder ^[Ref]

Internet Explorer 9 and lower does not support the placeholder attribute at all, while Opera 12 and lower do not support any CSS selector for placeholders.

The discussion about the best implementation is still going on. Note the pseudo-elements act like real elements in the Shadow DOM. A padding on an input will not get the same background color as the pseudo-element.

CSS selectors

User agents are required to ignore a rule with an unknown selector. See Selectors Level 3:

a group of selectors containing an invalid selector is invalid.

So we need separate rules for each browser. Otherwise the whole group would be ignored by all browsers.

::-webkit-input-placeholder { /* WebKit, Blink, Edge */
    color:    #909;
}
:-moz-placeholder { /* Mozilla Firefox 4 to 18 */
   color:    #909;
   opacity:  1;
}
::-moz-placeholder { /* Mozilla Firefox 19+ */
   color:    #909;
   opacity:  1;
}
:-ms-input-placeholder { /* Internet Explorer 10-11 */
   color:    #909;
}
::-ms-input-placeholder { /* Microsoft Edge */
   color:    #909;
}

::placeholder { /* Most modern browsers support this now. */
   color:    #909;
}

<input placeholder="Stack Snippets are awesome!">

change placeholder text color of textarea

For modern browsers, use just the ::placeholder pseudo element:

textarea::placeholder {
  color: #0bf;
}

Legacy and modern browsers:

textarea:-moz-placeholder, /* Firefox 18- */
textarea::-moz-placeholder, /* Firefox 19+ */
textarea:-ms-input-placeholder, /* IE 10+ */
textarea::-webkit-input-placeholder, /* Webkit based */
textarea::placeholder { /* Modern browsers */
  color: #0bf;  
}

<textarea placeholder="test"></textarea>

How to set the color of placeholder text?

Nobody likes the "refer to this answer" answers, but in this case it may help: Change an HTML5 input's placeholder color with CSS

Since it's only supported by a couple of browsers, you can try the jQuery placeholder plugin (assuming you can\are using jQuery). It allows you to style the placeholder text via CSS since it's really only a swap trick it does with focus events.

The plugin does not activate on browsers that support it, though, so you can have CSS that targets chrome\firefox and the jQuery plugin's CSS to catch the rest.

The plugin can be found here: https://github.com/mathiasbynens/jquery-placeholder

Cannot change the text color of Angular material input placeholder

To change the css of your placeholder, all you need to do is modify the color of your matInput placeholder. You can make use of the mat-input-element class in the matInput element to do this.

Ideally, I would also suggest you avoid using inline styles and use classes instead. It makes your code more readable as well.

HTML

<form #searchForm="ngForm" class="example-full-width mr-auto">
  <mat-form-field class="employee-search-field">
    <mat-label>Search for an Employee</mat-label>
    <input matInput [(ngModel)]="userIdInput" name="userIdInput" placeholder="Enter at least 2 characters of a name or ID"/>
  </mat-form-field>
</form>

In your css, add the below code.

.employee-search-field {
  width: 350px;
  font-size: 14px;
  margin-bottom: -15px;
}

.employee-search-field mat-label {
  color: white;
  /* add label text color here */
}

.employee-search-field .mat-input-element {
  color: white;
  /* add input text color here */
}

.employee-search-field .mat-input-element::placeholder {
  color: white;
  /* add placeholder css here */
}

Changing Placeholder Text Color with Swift

You can set the placeholder text using an attributed string. Just pass the color you want to the attributes parameter.

Swift 5:

let myTextField = UITextField(frame: CGRect(x: 0, y: 0, width: 200, height: 30))
myTextField.backgroundColor = .blue
myTextField.attributedPlaceholder = NSAttributedString(
    string: "Placeholder Text",
    attributes: [NSAttributedString.Key.foregroundColor: UIColor.white]
)

Swift 3:

myTextField.attributedPlaceholder = NSAttributedString(
    string: "Placeholder Text",
    attributes: [NSAttributedStringKey.foregroundColor: UIColor.white]
)

Older Swift:

myTextField.attributedPlaceholder = NSAttributedString(
    string: "Placeholder Text",
    attributes: [NSForegroundColorAttributeName: UIColor.white]
)
