# [Identity][Templates] Ensure placeholders don't overlap with text

Placeholder text on input textboxes overlaps with the label texts.

## Description

* As part of an accessibility fix, we started displaying placeholders on input elements.
* In some circumstances, these placeholders overlap with the labels on the input text boxes, making it problematic to read them.
* The fix addresses this by reducing the size of the placeholders and making inputs bigger to avoid any overlap.

Fixes dotnet/AspNetCore-ManualTests#3081

## Customer Impact

When the window size is small enough, customers could see overlapped text that's hard to read and is sometimes even impossible.

## Regression?

- [X] Yes
- [ ] No

8.0 since we introduced this behavior on 9.0 as part of accessibility fixes.

## Risk

- [ ] High
- [ ] Medium
- [x] Low

The attached videos serve as validation of the fix, in addition to that, the UI is completely customizable by customers.

## Verification

- [X] Manual (required)
- [ ] Automated
