Label as input-placeholder and autofill

b3nnu3 profile image Benjamin Schnoor ・1 min read

Everybody knows the fancy input placeholders that will move out of the input-field if you set the focus on it.

Input with label as placeholder

So it's relatively easy:

input:focus ~ label {/* stuff*/}
<input id="user"><label for="user">Input</label>

The problem

If your page is ssl encrypted and the user has used
your login-form before. The browsers will autofill your form.

But they wont really fill your form. Its just a preview.
And they will do it on page-load they dont need the focus.

If you use javascript to check if the form-value is filled, it will appear empty.

And in the end, the filled in preview-data, will overlap your label-/placeholder.

Input with overlapping text

The Solution

To prevent this, you could use a construct like the following.
So you will check for the placeholder. You should also set the color of the input-placeholder to transparent.

input:not(:placeholder-shown) ~ label,
input:focus ~ label {/* stuff*/}
<input placeholder="input" id="user"><label for="user">Input</label>

Hope that will help somebody. :D
