The site you linked uses a combination of CSS tricks to pull this off. First, it uses a background-image for the <input> element. Then, in order to push the cursor over, it uses padding-left.

In other words, they have these two CSS rules:

background: url(images/comment-author.gif) no-repeat scroll 7px 7px;
padding-left:30px;

Could you please describe more about top and left parameters (7px 7 px) and other attributes? That is must be helpful.
Advice: stop using and supporting IE 8.
how can I align the image to the right end of the input field?
The problem with background images is that Chrome's autofill removes the background image and makes the background yellow completely
To align to the right use: background-position: right;

The CSS solutions posted by others are the best way to accomplish this.

If that should give you any problems (read IE6), you can also use a borderless input inside of a div.

<div style="border: 1px solid #DDD;">
    <img src="icon.png"/>
    <input style="border: none;"/>
</div>

Not as "clean", but should work on older browsers.


a good addition to this answer. sometimes ie gives problems and this is a good way to solve one of them. worked for me albeit with a span instead.
Nice way to add more complex structures inside inputs!
@jonhue, I wouldn't recommend this unless you're still living in the previous decade and need to support IE6. Even then, I wouldn't call it "clean."
@harpo How would you include links inside inputs then?
Idk about this, if you click on the image, would it select/highlight/focus the input field?

A solution without background-images:

.icon { padding-left: 25px; background: url("https://static.thenounproject.com/png/101791-200.png") no-repeat left; background-size: 20px; }

Or for right to left icon

.icon-rtl { padding-right: 25px; background: url("https://static.thenounproject.com/png/101791-200.png") no-repeat right; background-size: 20px; }


A minor issue with this - the image is positioned over (z axis) the input, so it blocks clicks over it from focusing on the input (this can be observed in the snippet). It's possible to resolve by sending the image under the input
how about color, if I wish to add color as well along with icon ?

You can try this:

input[type='text'] {
    background-image: url(images/comment-author.gif);
    background-position: 7px 7px;
    background-repeat: no-repeat;
}

I find this the best and cleanest solution to it. Using text-indent on the input element:

#icon { background-image: url(../images/icons/dollar.png); background-repeat: no-repeat; background-position: 2px 3px; }


I'm supporting text-indent because padding-left will increase field's width and it'll overflow out of the parent element.
why did you put the style inline instead of in the #icon css?
@WylliamJudd That is just for demonstration purpose :)
why did you use id instead of class?

A simple and easy way to position an Icon inside of an input is to use the position CSS property as shown in the code below. Note: I have simplified the code for clarity purposes.

Create the container surrounding the input and icon. Set the container position as relative Set the icon as position absolute. This will position the icon relative to the surrounding container. Use either top, left, bottom, right to position the icon in the container. Set the padding inside the input so the text does not overlap the icon.

#input-container { position: relative; } #input-container > img { position: absolute; top: 12px; left: 15px; } #input-container > input { padding-left: 40px; }


Clean and simple, yes. You should also remove the input border with input { border: none; } and add the border to #input-container { border: 1px solid #000; } to make it look like the image is inside and actually part of the input.
@MarioWerner he pushed the image inside the input, no need to do border hacks, that's the beauty. I am going to use the idea.
This is an excellent comprehensive answer! saved me much time thank you for this

.icon{
background: url(1.jpg) no-repeat;
padding-left:25px;
}

add above tags into your CSS file and use the specified class.

This works for me:

input.valid { border-color: #28a745; padding-right: 30px; background-image: url('https://www.stephenwadechryslerdodgejeep.com/wp-content/plugins/pm-motors-plugin/modules/vehicle_save/images/check.png'); background-repeat: no-repeat; background-size: 20px 20px; background-position: right center; }


the image disappear when autocompleting on chrome
How do you make the image clickable, e.g. if using a "save" icon?
It worked for me for my hybrid app, I just made the whole input box clickable after inserting image.
can I use your code both for personal and commercial projects ?

use this css class for your input at start, then customize accordingly:

.inp-icon { background: url(https://i.imgur.com/kSROoEB.png)no-repeat 100%; background-size: 16px; }


do you know how to set click event only for this image.?

Jackson Kamya

I achieved this with the code below.

First, you flex the container which makes the input and the icon be on the same line. Aligning items makes them be on the same level.

Then, make the input take up 100% of the width regardless. Give the icon absolute positioning which allows it to overlap with the input.

Then add right padding to the input so the text typed in doesn't get to the icon. And finally use the right css property to give the icon some space from the edge of the input.

Note: The Icon tag could be a real icon if you are working with ReactJs or a placeholder for any other way you work with icons in your project.

.inputContainer { display: flex; align-items: center; position: relative; } .input { width: 100%; padding-right: 40px; } .inputIcon { position: absolute; right: 10px; }

Just use the background property in your CSS.

<input id="foo" type="text" />

#foo
{
    background: url(/img/foo.png);
}

I had situation like this. It didn't work because of background: #ebebeb;. I wanted to put background on the input field and that property was constantly showing up on the top of the background image, and i couldn't see the image! So, I moved the background property to be above the background-image property and it worked.

input[type='text'] {
    border: 0;
    background-image: url('../img/search.png');
    background-position: 9px 20px;
    background-repeat: no-repeat;
    text-align: center;
    padding: 14px;
    background: #ebebeb;
}

Solution for my case was:

input[type='text'] {
    border: 0;
    background: #ebebeb;
    background-image: url('../img/search.png');
    background-position: 9px 20px;
    background-repeat: no-repeat;
    text-align: center;
    padding: 14px;
}

Just to mention, border, padding and text-align properties are not important for the solution. I just replicated my original code.


This is super old and I hope maybe you've learned since over a year ago, but background is a shorthand property name which you use to cover all the background properties at once: background: [color] [image url] [repeat] [position], and that's why your color was overwriting everything. You could also have left it in place and renamed the property to background-color
@borbulon yes you are right. it's almost always best to use shorthand property name, totally agree on that. But purpose of this post is to point out that order of properties sometimes matters, and those 'small' CSS rules can be frustrating a lot, especially to newcomers in development.
Totally agree, but the point still stands: background is a shorthand property name. A better fix would have been to not use the shorthand, but use background-color for the color property (assuming you want both a color and an image).

Using with font-icon

<input name="foo" type="text" placeholder="&#61447;">

OR

<input id="foo" type="text" />

#foo::before
{
  font-family: 'FontAwesome';
  color:red;
  position: relative;
  left: -5px;
  content: "\f007";    
}

Seems that ::before can not be applied of input element.
seems this css works only on non-input element, like div.

 <label for="fileEdit">
    <i class="fa fa-cloud-upload">
    </i>
    <input id="fileEdit" class="hidden" type="file" name="addImg" ng-file-change="onImageChange( $files )" ng-multiple="false" accept="{{ contentType }}"/>
  </label>

For example you can use this : label with hidden input (icon is present).


Good solution, but please add an explanation for your solution.

I was able to add an icon to an input field by adding the icon as a background image through CSS. From there, you can adjust the size of the image using the background-size property and finally, position the element with the background-position-x and background-position-y properties. I've shared a code snippet below and linked to a working example in Codepen here:

body { margin: 0; padding: 0; font-family: sans-serif; } .input-container { padding: 50px; } input { box-sizing: border-box; width: 250px; padding-left: 36px; height: 48px; background-image: url('https://image.shutterstock.com/image-vector/apple-icon-vector-fruit-symbol-260nw-1466147615.jpg'); background-size: 20px; background-position-x: 10px; background-position-y: 50%; background-repeat: no-repeat; border-radius: 15px; } Icon Inside Input Field

I didn't want to change the background of my input text neither it will work with my SVG icon.

What i did is adding negative margin to the icon so it appear inside the input box

and adding same value padding to the input so text won't go under the icon.

<div class="search-input-container">

  <input
    type="text"
    class="search-input"
    style="padding-right : 30px;"
  />

  <img 
    src="@/assets/search-icon.svg" 
    style="margin-left: -30px;"
   />

</div>

*inline-style is for readability consider using classes

.input_container { display: flex; border-bottom: solid 1px grey; transition: border-color 0.1s ease-in; background: white; } .input { color: blue; display: block; width: calc(100% - 20px); border: none; outline: none; padding: 8px 16px; } .input_img { flex-basis: 20px; display: inline-block; padding: 8px 16px; cursor: pointer; }


Good solution, but please add an explanation for your solution.

You could go for a different approach which also allows you to click it and have it do a function. Have a look at the example below:

<div id="search-bar">
  <input placeholder="Search or Type a URL">
  <button><i class="fas fa-search"></i></button>
</div>

#search-bar {
  display: flex;
  justify-content: center;
  position: fixed;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  margin: auto;
  height: 60px;
}
#search-bar > input {
  width: 750px;
  font-size: 30px;
  padding: 20px;
  border-radius: 50px 0px 0 50px;
  border: none;
  border-top: 1px solid #000;
  border-bottom: 1px solid #000;
  border-left: 1px solid #000;
  background: #fff; /* CSS Edit Here */
}
#search-bar > button {
  background: #fff;
  border: none;
  font-size: 30px;
  border-right: 1px solid #000;
  border-top: 1px solid #000;
  border-bottom: 1px solid #000;
  border-radius: 0 50px 50px 0 ;
  padding-right: 20px;
}

The css background solutions do it for most cases, but it has a problem with webkit (chrome) autocomplete where the icon disappear.

There are other solutions that includes changing the html/dom structure by wrapping the input in a div and adding an extra element (img, div, or similar). I don't like does solutions because you need to tweak the elements css with absolute positions and/or resizing by pixel to get the right place. Or recreate the input border to "merge" input and img in one.

So this solution is based on css background image not applied over input element, but applied over a wrapper div.

HTML:

<div class="input-email">
    <input type="text" placeholder="Email" name="email" id="email">
</div>

CSS:

.input-email {
    background: url(/assets/images/email.svg) no-repeat scroll 14px 11px;
    display: inline-block;
} 

.input-email input{
    padding-left: 40px;
    background-color: transparent !important;
}

input:-webkit-autofill, input:-webkit-autofill:hover, 
input:-webkit-autofill:focus, input:-webkit-autofill:active {
    transition: background-color 5000s ease-in-out 0s;
}

This way with .input-email class I define my icon image as div background (not affected by webkit autocomplete background). Next .input-email input definition I pad left the input element to give space for the image and set it as transparent (this works when autocomplete is not applied) Finally with webkit-autofill classes I remove with transition the background-color set by the autocomplete.

Note: at point 2 I set transparent !important because this -internal-autofill-selected gets rendered at browser and I couldn't overwrite it without setting my also as !important:

input:-internal-autofill-selected {
    background-color: -internal-light-dark(rgb(232, 240, 254), rgba(70, 90, 126, 0.4)) !important;
}

I got my solution from this post https://www.py4u.net/discuss/1069380 I have make some tweaks, though major credits are to them.

This works for me for more or less standard forms:

  <button type="submit" value="Submit" name="ButtonType" id="whateveristheId" class="button-class">Submit<img src="/img/selectedImage.png" alt=""></button>

Not buttons, inputs.
