When adding CSS styles to text on an HTML page, it’s usually best to keep it subtle, to make sure that the content on your page is easy to read. But sometimes you may want to make a small block of text stand out a little more than the rest. In this post, I’ll go over how to use the
text-shadow CSS property to add a drop shadow to your text.

There are some basic ways to make your text stand out. You can make it bold, change the color, or use different font-sizes.
Another option is to use the
text-shadow property to add a drop shadow. There are four values used with this property. Two are required, the
offset-y, and two are optional, the
/* offset-x | offset-y | blur-radius | color */ text-shadow: 2px 2px 4px green;
Let’s go over how to define each value.
offset-x value determines how far away, from the element, the shadow will appear on the x-axis, which runs left to right. The second value, the
offset-y, determines the distance of the shadow on the y-axis, which runs top to bottom.
These values can be defined with any length data type, which is a number followed by any unit used to represent a distance value (e.g.
rem or a percentage). Also, when using a property with multiple values, each has to be separated by a space.
/* offset-x | offset-y */ text-shadow: 2px 2px;
Since both the
offset-y values are required, if you add only value, you won’t see any change. But if you only want a shadow on the x-axis, then set the
offset-y value to
0 or vice versa.
text-shadow: 2px 0px; /* will only show the shadow on the x-axis */ text-shadow: 0px 2px; /* will only show the shadow on the y-axis */
I used to always get the direction of the x- and y-axis mixed up until I saw an example using Beyoncé’s “Irreplaceable” lyrics as a reminder. In the song, she sings to her ex, “to the left to the left, everything you own in the box to the left.” So, ex (or x) to the left!
If you only define the
offset-y values, the shadow will look exactly like a copy of the text.
To create a softer shadow effect, add a third value, the
blur-radius. This will blur the edges of the shadow. Any length data type can be used here as well. The larger the value, the bigger and more transparent the blur effect.
The last value is used to change the shadow from the default black colour to any other colour by adding a color value (e.g. keyword, hex code).
Putting it all together
Most of the time, text-shadow effects are used add a subtle drop shadow and not quite like the example below. But for demonstration and testing, using values that create a more prominent style will make it easier to see what each value does.
To make a
text-shadow effect a little more subtle, I generally use a dark gray color or something that matches to the background colour, rather than pure black. This will create a softer shadow. (Note that the hex values in the example is using the shorthand notation.)
For the other values, I find that 1–3px is usually enough to give you just a bit of a shadow effect without overwhelming the text. Though there are always exceptions to the rule so I would suggest playing around with different values to get the effect you’re looking for. But in a nutshell, this is how you add a drop shadow to your text.
And that’s it!
