When working with layer styles, there are a couple useful things to know that will let you maximize your results. For example, you can rearrange the order in which styles are applied, temporarily disable specific styles, or even reset all the styles applied to a particular layer.
Temporarily hide a single style
When a layer style is turned off, it no longer shows on the layer but is still visible in the Tool Options pane. Turning the layer style back on restores all of its previous settings.
Choose the Style tool by doing one of the following:
A quick way to apply the same layer style to multiple layers is by using layer style presets. However, you can also apply the same layer style to multiple layers by simply copying it over.
Choose Format > Styles > Copy Styles (from the Format menu at the top of your screen).
In the Layers sidebar,
Control ⌃ – click the layer from which you’d like to copy a style and choose Styles > Copy Styles.
Select the layer to which you’d like to apply the copied style.
To paste the style, do one of the following:
Choose Format > Styles > Paste Styles (from the Format menu at the top of your screen).
In the Layers sidebar, Control ⌃ – click the layer to which you’d like to paste the style and choose Styles > Paste Styles.
Rearrange the order of layer styles
If you apply two or more of the same layer style to a single layer, you can rearrange the order in which they are applied.
To rearrange layer styles, click and drag a style up or down the list of styles.
Flatten layer styles
Flattening (or merging) all the styles applied to a layer can be useful when you want to make edits to the layer together with the layer style. For example, you might want to erase part of a layer as well as the shadow applied to it. Without flattening, the shadow would adapt to the new shape of the layer.
Choose the Style tool by doing one of the following:
Press and hold the Option ⌥ key and, in the
Tool Options pane, click the Flatten Styles button at the bottom.
You can also choose Format > Styles > Flatten Styles (from the Format menu at the top of your screen), or in the Layers sidebar,
Control ⌃ – click the layer you’d like to flatten and choose Styles > Flatten Styles.
