How to style icon color, size, and shadow of Font Awesome Icons

问题

How could I style the color, size and shadow of icons from Font Awesome\'s Icons?

For example, Font Awesome\'s site will show some icons in white and some in red but won\'t show the CSS for how to style them that way ...

回答1:

Given that they're simply fonts, then you should be able to style them as fonts:

#elementID {
    color: #fff;
    text-shadow: 1px 1px 1px #ccc;
    font-size: 1.5em;
}

回答2:

You can also just add style inline:

<i class="icon-ok-sign" style="color:green"></i>

<i class="icon-warning-sign" style="color:red"></i>

回答3:

If you are using Bootstrap at the same time, you can use:

<i class="fa fa-check-circle-o fa-5x text-success" ></i>

Otherwise:

<i class="fa fa-check-circle-o fa-5x" style="color:green"></i>

Looks like the FontAwesome icon color responds to text-info, text-error, etc.

<div style="font-size: 44px;">
   <i class="icon-umbrella icon-large text-error"></i>
</div>

回答5:

inyour.css file:

    *.icon-white {color: white}
    *.icon-silver {color: silver}

inyour.html file:

    <a><i class="icon-book icon-white"></i> Book</a>
    <a><i class="icon-ok-sign icon-silver"></i> OK</a>

There is a really simple way to change the colour of Font Awesome icons.

<!-- Font Awesome insert code -->
<script src="https://use.fontawesome.com/49b98aaeb5.js"></script>
<!-- End -->
<i class="fa fa-thumbs-up fa-5x" aria-hidden="true" style="color:#00cc6a"></i>
<i class="fa fa-thumbs-up fa-4x" aria-hidden="true" style="color:#00cc6a"></i>
<i class="fa fa-thumbs-up fa-3x" aria-hidden="true" style="color:#00cc6a"></i>
<i class="fa fa-thumbs-up fa-2x" aria-hidden="true" style="color:#00cc6a"></i>
<i class="fa fa-thumbs-up" aria-hidden="true" style="color:#00cc6a"></i>

You can change the hex code to your preference. NOTE: The text colour will change the icon colour as well unless there is a style="color:#00cc6a" within the i tag.

Using FA 4.4.0 adding

.text-danger
    color: #d9534f

to the document css and then using

 <i class="fa fa-ban text-danger"></i>

changes the color to red. You can set your own for any color.

http://fortawesome.github.io/Font-Awesome/examples/

<i class="icon-thumbs-up icon-3x main-color"></i>

Here I have defined a global style in my CSS where main-color is a class, in my case it is a light blue hue. I find that using inline styles on Icons with Font Awesome works well, esp in the case when you name your colors semantically, i.e. nav-color if you want a separate color for that, etc.

In this example on their website, and how I have written in my example as well, the newest version of Font Awesome has changed the syntax slightly of adjusting the size.Before it used to be:

icon-xxlarge

where now I have to use:

icon-3x

Of course, this all depends on what version of Font Awesome you have installed on your environment. Hope this helps.

回答9:

In FontAwesome 4.0, the classes change to 'fa-2x', 'fa-3x'.

回答10:

Simply you can define a class in your css file and cascade it into html file like

<i class="fa fa-plus fa-lg green"></i> 

now write down in css

.green{ color:green}

回答11:

For Size : fa-lg, fa-2x, fa-3x, fa-4x, fa-5x.

For Color : <i class="fa fa-link fa-lg" aria- hidden="true"style="color:indianred"></i> For Shadow : .fa-linkedin-square{ text-shadow: 3px 6px #272634; }``

回答13:

Just target font-awesome predefined class name

in ex:

HTML

<i class="fa fa-facebook"></i> 

CSS

i.fa {
    color: red;
    font-size: 30px;
}

回答14:

I had the same problem when I tried to use the icons directly from BootstrapCDN (the easiest way). Then I downloaded the CSS file and copied it to my site's CSS folder the CSS file (Described under the 'easy way' in font awesome documentation), and everything started working as they should.

Credit: Can I change the color of Font Awesome's icon color?

(this answer builds on that answer)

(for the bookmark icon, for example:)

inyour.css file:

.icon-bookmark.icon-white {
    color: white;
}

inyour.html file:

<div class="icon-bookmark icon-white"></div>

回答16:

Wrap the i tag in p or span, then you can use bootstrap css class

<p class="text-success"><i class="fa fa-check"></i></p>

回答17:

For Font Awesome 5 SVG version, use

filter: drop-shadow(0 0 3px rgba(0,0,0,0.7));

回答18:

As it has been pointed out, font awesome icons are text, consequently you style it using the appropriate CSS attributes. For example:

.fa-twitter-square {
    font-size: 15px;
    color: red;
}

If, as it happens quite a bit to me, the icon size doesn't change at all, add "!important" to the font-size attribute.

.fa-twitter-square {
    font-size: 15px !important;
    color: red;
}

回答19:

Dynamically change the css properties of .fa-xxx icons:

<li class="nws">
<a href="#NewsModal" class="urgent" title="' + title + '" onclick=""><span class="label label-icon label-danger"><i class="fa fa-bolt"></i></span>' 
</a>
</li>
<script>
  $(document).ready(function(){
   $('li.nws').on("focusin", function(){
    $('.fa-bolt').addClass('lightning');
   });
 });
</script>

<style>
.lightning{ /*do something cool like shutter*/}
</style>

回答20:

text-shadow: 1px 1px 3px rgba(0,0,0,0.5);

For Sizing Icons

Both our Web Fonts + CSS and SVG + JS frameworks include some basic controls for sizing icons in the context of your page’s UI.

you can use like

<i class="fas fa-camera fa-xs"></i>
<i class="fas fa-camera fa-sm"></i>
<i class="fas fa-camera fa-lg"></i>
<i class="fas fa-camera fa-2x"></i>
<i class="fas fa-camera fa-3x"></i>
<i class="fas fa-camera fa-5x"></i>
<i class="fas fa-camera fa-7x"></i>
<i class="fas fa-camera fa-10x"></i>

https://fontawesome.com/how-to-use/on-the-web/styling/sizing-icons

回答22:

I would not advice you to use built in font-awesome styling like the fa-5x etc; for fear they may change it and you would have to keep chainging your application code to meet up with the latest standard. You simply avoid this by giving each font-awesome class you want to style uniformly the same class say:

<i class="fa fa-facebook-square fa-sabi-social-icons" aria-hidden="true"></i>
<i class="fa fa-twitter-square fa-sabi-social-icons" aria-hidden="true"></i>
<i class="fa fa-google-plus-square fa-sabi-social-icons" aria-hidden="true"></i>

Here the class is fa-sabi-social-icons

Then in your css you can the style the fonts using the same css rules you would style a normal font with. e.g

.fa-sabi-social-icons {
     color: //your color;
     font-size: // your font-size in px, em or %;
     text-shadow: 2px 2px #FF0000;
}

That should get your font-awesome fonts styled
