HTML / CSS How to add image icon to input type="button"?

I'm using the below CSS, but it puts an image in the center of the button. Any way to left or right align an icon using <input type="button">, so that the text and the image fit and align nicely?

background: url('/common/assets/images/icons/16x16/add.png');
background-position:center;
background-repeat:no-repeat;

If you absolutely must use input, try this:

background-image: url(...);
background-repeat: no-repeat;
background-position: <left|right>;
padding-<left|right>: <width of image>px;

It's usually a little easier to use a button with an img inside:

<button type="submit"><img> Text</button>

However the browser implementations of button for submitting are inconsistent, as well as the fact that all button values are sent when button is used - which kills the "what button clicked" detection in a multi-submit form.

This should do do what you want, assuming your button image is 16 by 16 pixels.

<input type="button" value="Add a new row" class="button-add" />

input.button-add {
    background-image: url(/images/buttons/add.png); /* 16px x 16px */
    background-color: transparent; /* make the button transparent */
    background-repeat: no-repeat;  /* make the background image appear only once */
    background-position: 0px 0px;  /* equivalent to 'top left' */
    border: none;           /* assuming we don't want any borders */
    cursor: pointer;        /* make the cursor like hovering over an <a> element */
    height: 16px;           /* make this the size of your image */
    padding-left: 16px;     /* make text start to the right of the image */
    vertical-align: middle; /* align the text vertically centered */
}

Example button:

Update

If you happen to use Less, this mixin might come in handy.

.icon-button(@icon-url, @icon-size: 16px, @icon-inset: 10px, @border-color: #000, @background-color: transparent) {
    height: @icon-size * 2;
    padding-left: @icon-size + @icon-inset * 2;
    padding-right: @icon-inset;
    border: 1px solid @border-color;
    background: @background-color url(@icon-url) no-repeat @icon-inset center;
    cursor: pointer;
}

input.button-add {
    .icon-button("http://placehold.it/16x16", @background-color: #ff9900);
}

The above compiles into

input.button-add {
  height: 32px;
  padding-left: 36px;
  padding-right: 10px;
  border: 1px solid #000000;
  background: #ff9900 url("http://placehold.it/16x16") no-repeat 10px center;
  cursor: pointer;
}

JSFiddle

<button type="submit" style="background-color:transparent; border-color:transparent;"> 
  <img src="images/button/masuk.png" height="35"/>
</button>
<button type="reset" style="background-color:transparent; border-color:transparent;"> 
  <img src="images/button/reset.png" height="35"/>
</button>

I hope this helps you.

If you're using spritesheets this becomes impossible and the element must be wrapped.

.btn{
    display: inline-block;
    background: blue;
    position: relative;
    border-radius: 5px;
}
.input, .btn:after{
    color: #fff;
}
.btn:after{
    position: absolute;
    content: '@';
    right: 0;
    width: 1.3em;
    height: 1em;
}
.input{
    background: transparent;
    color: #fff;
    border: 0;
    padding-right: 20px;
    cursor: pointer;
    position: relative;
    padding: 5px 20px 5px 5px;
    z-index: 1;
}

Check out this fiddle: http://jsfiddle.net/AJNnZ/

you can try insert image inside button http://jsfiddle.net/s5GVh/1415/

<button type="submit"><img src='https://aca5.accela.com/bcc/app_themesDefault/assets/gsearch_disabled.png'/></button>

What I would do is do this:

Use a button type

 <button type="submit" style="background-color:rgba(255,255,255,0.0); border:none;" id="resultButton" onclick="showResults();"><img src="images/search.png" /></button>

I used background-color:rgba(255,255,255,0.0); So that the original background color of a button goes away. The same with the border:none; it will take the original border away.

you can try this trick!

1st) do this:

<label for="img">
   <input type="submit" name="submit" id="img" value="img-btn">
   <img src="yourimage.jpg" id="img">
</label>

2nd) style it!

<style type="text/css">
   img:hover {
	   cursor: pointer;
   }
   input[type=submit] {
	   display: none;
   }
</style>

It is not clean but it will do the job!

Simply add icon in button element here is the example

   <button class="social-signup facebook"> 
     <i class="fa fa-facebook-official"></i>  
      Sign up with Facebook</button>

This is the minimal style needed, fitting the image to the default button size:

<input type="button" value=" " style="background-image: url(http://www.geppoz.eu/geppoz.png);background-size:100% 100%;">

the "spaced" value is needed to keep baseline alignment, just in case you need it...

sshow's answer did it for me, too:

navigation.css:

[...]

.buttonConfiguration {
	width: 40px;
	background-color: red; /* transparent; */
	border: none;
	color: white;
	padding: 5px 10px;
	text-align: center;
	text-decoration: none;
	display: inline-block;
	font-family: corbel;
	font-size: 12px;
	font-weight: normal;
	margin: 1px 1px;
	cursor: pointer;

	background-image: url('../images/icons5/gear_16.png');
	background-position: center; /* 0px 0px; */
	background-repeat: no-repeat;
	vertical-align: middle;
}

[...]

frameMenu.php:

[... PHP, Javascript and HTML code ...]

<!-- <li><a target="frameBody" href="admin/conf/confFunctions.php"><input type="button" class="buttonSuperAdmin" value="<?= $oLanguage->getExpression('confSettings', 'title', 'C e n t e r s') ?>"></a> -->
<li><a target="frameBody" href="admin/conf/confFunctions.php"><input type="button" class="buttonConfiguration" value=""></a>
<ul>
<li><a target="frameBody" href="admin/conf/getglobals.php "><input type="button" class="buttonSuperAdminSub" value="<?= $oLanguage->getExpression('centerSettings', 'confAdmin1', 'GetGlobals') ?>"></a></li>
<li><a target="frameBody" href="admin/conf/getcwd.php "><input type="button" class="buttonSuperAdminSub" value="<?= $oLanguage->getExpression('confSettings', 'centerAdmin2', 'GetCWD') ?>"></a></li>
</ul>
</li>

I have tested this successfully under the lastest versions of Firefox and Chrome (as of February 9th, 2019).

This works well for me, and I'm handling hover and click CSS as well (by changing background color):

HTML (here showing 2 images, image1 on top of image2):

<button class="iconButton" style="background-image: url('image1.png'), url('image2.png')"
  onclick="alert('clicked');"></button>

CSS (my images are 32px X 32px, so I gave them 4px for padding and a 5px border rounding):

.iconButton {
    width: 36px;
    height: 36px;
    background-color: #000000;
    background-position: center;
    background-repeat: no-repeat;
    border: none;
    border-radius: 5px;
    cursor: pointer;
    outline: none;
}

.iconButton:hover {
    background-color: #303030;
}

.iconButton:active {
    background-color: #606060;
}

button::-moz-focus-inner {
    border: 0;
}

<img src="http://www.pic4ever.com/images/2mpe5id.gif">
            <button class="btn btn-<?php echo $settings["button_background"]; ?>" type="submit"><?php echo $settings["submit_button_text"]; ?></button>
