Briefly
The readonly
attribute is added to form fields that the user cannot edit. They will be read-only.
Example
In this example, you cannot edit your birth date:
<form> <div class="group"> <input type="date" value="1995-04-04" readonly="readonly" id="date"> <label for="date">Birth date</label> </div></form>
<form> <div class="group"> <input type="date" value="1995-04-04" readonly="readonly" id="date"> <label for="date">Birth date</label> </div> </form>
How to write
The readonly
attribute is boolean; it can be added with the value: readonly
, or without it — <input type
.
The readonly
attribute can be used for <textarea>
and <input>
with the following types:
text
,search
,url
,tel
,email
,password
,date
,month
,week
,time
,datetime
,- local number
.
Not used:
- with the tag
<select>
; - with any type of buttons (even if it is an image);
- if the field has the
hidden
attribute.
Also, for fields with the readonly
attribute, the required
attribute will not work.
How to understand
There is a difference between disabled
and readonly
. Thus, fields that are read-only (readonly
) can still receive focus and will be submitted along with the form, unlike inactive fields (disabled
).
Tips
💡 A field with the readonly
attribute can be styled using the pseudo-class :read
, while fields without this attribute can be styled with :read
.
