**`Set Element Attribute`** is a [regular block](/app-editor/page-flow/block-anatomy.md#regular-block) that allows you to set the value of any [HTML attribute](https://en.wikipedia.org/wiki/HTML_attribute) in elements on a page or form.

{% hint style="success" %}
Refer to the [Set Element Attribute in Data Design](/app-editor/page-flow/toolbox-blocks/set-element-attribute-in-data-design.md) block for dynamically generated content.
{% endhint %}

The block comes in two modes which are discussed below.

## Mode 1 <a href="#mode-1" id="mode-1"></a>

<div align="left"><figure><img src="/files/gA83qdIwMkt6Vs6K5jT4" alt="" width="383"><figcaption><p>Set Element Attribute (Mode 1)</p></figcaption></figure></div>

The Mode 1 version of the Set Element Attribute block consists of (from left to right):

* *Attribute:* [Input](/app-editor/page-flow/block-anatomy.md#input) configuration setting to specify the [HTML attribute](https://en.wikipedia.org/wiki/HTML_attribute) to set or change the value of.
* *Element*: [Selectable Input](/app-editor/page-flow/block-anatomy.md#selectable-input) to choose the element you want to set the attribute of.
* *Data*: [Value Parameter](/app-editor/page-flow/block-anatomy.md#value-parameters) that accepts the value for the attribute being set (of type [*text*](/app-editor/page-flow/references/value-types.md)*)*

## Mode 2 <a href="#mode-2" id="mode-2"></a>

<div align="left"><figure><img src="/files/aKMWWaZfSbrjiw5zNR90" alt="" width="383"><figcaption><p>Set Element Attribute (Mode 2)</p></figcaption></figure></div>

The Mode 2 version of the Set Element Attribute block consists of (from left to right):

* *Attribute*: [Value Parameter](/app-editor/page-flow/block-anatomy.md#value-parameters) that accepts a *text* value representing the [HTML attribute](https://en.wikipedia.org/wiki/HTML_attribute) to set or change the value of.
* *Element*: [Value Parameter](/app-editor/page-flow/block-anatomy.md#value-parameters) that accepts either a [*text*](/app-editor/page-flow/references/value-types.md) value in the form of a [CSS Selector](https://developer.mozilla.org/en-US/docs/Learn/CSS/Building_blocks/Selectors) or an [*element*](/app-editor/page-flow/references/value-types.md) value[.](https://developer.mozilla.org/en-US/docs/Learn/CSS/Building_blocks/Selectors) The Element block comes pre-attached for your convenience but can be removed and customized.
* *Data*: [Value Parameter](/app-editor/page-flow/block-anatomy.md#value-parameters) that accepts the value for the attribute being set (of type [*text*](/app-editor/page-flow/references/value-types.md)*)*

## Usage Examples

The image below shows an example of the Mode 1 version where a [Link](/app-editor/page-editor/built-in-elements/link.md) element is selected for which the *Attribute* input configuration is set to [href](/app-editor/page-editor/built-in-elements/link.md#href) and the *Data* value parameter is attached to a Text block containing the Zingy website URL.&#x20;

<div align="left"><figure><img src="/files/LItY9Sv8VcwidUfFlAid" alt="" width="563"><figcaption><p>Example of Set Element Attribute Mode 1</p></figcaption></figure></div>

In the next example we see a Mode 2 version where the *Element* value parameter is attached to a Text block containing a [CSS Selector](https://developer.mozilla.org/en-US/docs/Learn/CSS/Building_blocks/Selectors) that selects the same [Link](/app-editor/page-editor/built-in-elements/link.md) element and sets the same attribute: [href](/app-editor/page-editor/built-in-elements/link.md#href). This time the *Data* value parameter is attached to a Variable block for variable named a.
