Boost Your Front‑End Workflow: 10 Photoshop Tricks Every Developer Should Know

Essential Photoshop Panels for Front‑End Work

Open the Properties , Info and Layers panels from the Window menu and dock them on the right side. These panels provide immediate access to layer attributes, dimensions and color information needed for slicing and CSS extraction.

Quick Layer Selection Shortcut

With the Move tool (V) active, press Option + Right‑Click on macOS or Alt + Right‑Click on Windows to pick any layer directly, without enabling “Auto‑Select”. Combine the click with Option + Scroll (or Alt + Scroll) to zoom while selecting.

Using the Properties Panel

View text layer font size and color.

Inspect shape fill color, corner radius and other vector attributes.

Read the width and height of smart objects.

Measuring Dimensions with the Info Panel

Select a layer, then press Command + T (Windows: Ctrl + T) to open the Transform handles. The Info panel displays the exact width and height of the layer. Press Esc to exit the transform without applying changes.

Eyedropper (I) Tool Tips

Click to copy a color; the value appears in the Info panel.

Drag while holding the left button to see whether the sampled area is a solid color or a gradient.

Right‑click the sampled point and choose “Copy Hex Color” to obtain a CSS‑ready hex code.

Set the layer opacity to 100 % before sampling to avoid altered values.

Hold Shift while sampling to collect multiple colors; they are listed sequentially in the Info panel.

Extracting Margin Distances

With the Move tool active, hold Command (Windows: Ctrl) and move the cursor near another layer. Photoshop draws purple distance annotations between the hovered layer and the selected layer, showing the margin values.

Copying CSS from a Layer

Right‑click a layer in the Layers panel and choose “Copy CSS”. The clipboard receives a CSS snippet that includes border‑radius, background‑color, opacity, box‑shadow, dimensions, positioning and z‑index. Example:

.roundedRect_584 {
  border-radius: 15px;
  background-color: rgb(0,0,0);
  opacity: 0.302;
  box-shadow: 6px 10.392px 121.83px 9.17px rgba(79,48,193,0.004);
  position: absolute;
  left: 283px;
  top: 306px;
  width: 136px;
  height: 32px;
  z-index: 34;
}

.gradientRect_1 {
  background-image: -moz-linear-gradient(90deg, rgb(255,255,255) 0%, rgba(255,255,255,0) 100%);
  background-image: -webkit-linear-gradient(90deg, rgb(255,255,255) 0%, rgba(255,255,255,0) 100%);
  background-image: -ms-linear-gradient(90deg, rgb(255,255,255) 0%, rgba(255,255,255,0) 100%);
  position: absolute;
  left: 348px;
  top: 572px;
  width: 113px;
  height: 78px;
  z-index: 25;
}

Duplicating a Layer into a New Document

Select the target layer or group in the Layers panel.

Right‑click and choose “Duplicate Layer”.

In the dialog, set “Document” to “New” and confirm.

The duplicated layer opens in a new document, allowing independent cropping, transformation or merging without affecting the original file.

Asset Generator for Automatic Export

Enable the generator via Preferences → Generator → Enable Generator , then activate File → Generate → Image Assets . Rename layers with a file‑type suffix to define export parameters. Examples: logo.png – PNG‑32 with transparency. logo.png8 – PNG‑8. logo.png24 – PNG‑24 without transparency. img/logo.png24 – Saves inside an img subfolder. logo.jpg – JPEG at 90 % quality. logo.jpg8 – JPEG at 80 % quality. 50% [email protected] – Scales the output to 50 % of the original size. 50% [email protected] + 100% [email protected] – Generates multiple sizes using “+” or “,” as separators.

Fine‑Tuning Exported Icons

When using rem units, add a 1‑pixel transparent border around PNG icons to prevent clipping. Since the Asset Generator cannot add this border, use Export As**, increase the canvas size by 2 pixels (1 px on each side), and export the adjusted image.
