<p class="main-paragraph">Every object you create in Penpot’s <a href="/user-guide/workspace-basics/#viewport">viewport</a> is a layer. Rectangles, ellipses, boards or text boxes are layers that you can use to build your design.</p>
<h2 id="pages">Pages</h2>
<p>Pages allow you to organize layers into separate sections inside a file, and are shown in separate tabs. Subdividing a file into pages gives you the ability to split your file into logically different sections so that you can organise your work. For instance, you can use pages to separate stages of the design process but keep them in the same document. Different screen sizes, features or atomic design categories are other common ways to use pages. </p>
<p>You can add, remove or rename pages to suit your needs.</p>
<p><strong>Layers:</strong> Layers are the different objects that you can place at the design viewport. At the layers panel you can see all the layers of a file page. Drag the layers to arrange them to different positions.</p>
<li>Select a layer and press top/bottom arrows while pressing <kbd>Ctrl/⌘</kbd> to move them in the layers list.</li>
<li>Press <kbd>tab</kbd> to change the layer selection to the next layer.</li>
<li>Press <kbd>tab</kbd> + <kbd>Shift/⇧</kbd> to change the layer selection to the previous layer.</li>
<li>If the layer contains other layers, press <kbd>Enter</kbd> to select the first layer inside the group and <kbd>Enter</kbd>+ <kbd>Shift/⇧</kbd> to move a level up.</li>
</ul>
<p>Layers are displayed from the bottom to the top of the layer stack, with layers above on the stack being shown on top in the image.</p>
<h2 id="hide-lock">Hide and lock layers</h2>
<p>Click on the eye icon to change the visibility of a layer. Click on the lock icon to lock or unlock a layer. A locked layer can not be modified.</p>
<p>To create a layer you have to select the type of layer by clicking the selected tool (board, rectangle, ellipse, text, image, path or curve) at the toolbar. Then you usually have to click and drag your mouse on the viewport. </p>
<p>Hold <kbd>Shift/⇧</kbd> while creating an ellipse or a rectangle to maintain equal width and height.</p>
<p>There are a couple ways to delete a layer. </p>
<ol>
<li>You can press <kbd>Supr/⌫</kbd> to delete a selected layer. </li>
<li>If you press right click over a selected layer at the viewport or at the layers panel you can use the option at the layer menu.</li>
</ol>
<h2 id="select-layers">Select layers</h2>
<p>The simplest way to select a layer is to click on it. Make sure that you have the “move” pointer selected at the toolbar. </p>
<p>To select multiple layers you can click and drag around the layers you want to select. You can also click more than one layer while pressing <kbd>Shift/⇧</kbd>. If you hold <kbd>Shift/⇧</kbd> and click you can deselect layers individually.</p>
<h3>Select layers ignoring groups (deep selection)</h3>
<p>If you want to select an element that is difficult to reach because it is under a group of elements, hold <kbd>Ctrl/⌘</kbd> to make the selection ignore group areas and treat all the objects as being at the same level.</p>
<p>To <strong>select a layer inside a group</strong> you do double click. First click selects the group, second click selects a layer.</p>
<h3>Select layer menu</h3>
<p>At the dropdown menu (right click on a layer to show it) there's the option "Select layer" that allows the user to select one layer among the ones that are under the cursor's location.</p>
<p>Grouped layers can be moved, transformed or styled at the same time. </p>
<ul>
<li><strong>Group:</strong> To group two or more layers, select them and then press <kbd>Ctrl/⌘</kbd> + <kbd>G</kbd>. You can also use the option at the layers menu that you can open with right click.</li>
<li><strong>Ungroup:</strong> Press <kbd>Shift/⇧</kbd> + <kbd>G</kbd> or use the option at the layers menu that you can open with right click over the selected group.</li>
<p>A mask is a layer that does a clipping and only shows parts of a layer or multiple layers that fall within its shape. </p>
<ul>
<li><strong>Mask layers:</strong> Select more than one layer or a group of them. Then you can apply the masking using the option at the layers menu or by pressing <kbd>Ctrl/⌘</kbd> + <kbd>M</kbd>. The shape that is at the lowest level at the layer list will be used as a mask. </li>
<li><strong>Unmask layers:</strong> Select a mask and then press <kbd>Shift/⇧</kbd> + <kbd>Ctrl/⌘</kbd> + <kbd>M</kbd> or use the option at the layers menu.</li>
<p>To move one or more layers on the viewport you have to select them first and then click and drag the selection where you want to place them. You can also use the design panel to set a precise position relative to the viewport or the board.</p>
<p>To resize a selected layer you can use the handles at the edges of the selection box. Make sure the cursor is in resizing mode. You can also use the design panel where you can link width and height.</p>
<ul>
<li>Hold <kbd>Shift/⇧</kbd> while resizing the object to preserve its aspect ratio.</li>
<li>Hold <kbd>Alt/⌥</kbd> while resizing the object to do it from the center and resize simultaneously two opposite sides.</li>
<p>To rotate selected layers you can use the handles at the edges of the selection box. Make sure the cursor is in rotation mode. If you hold <kbd>Ctrl/⌘</kbd> while rotation the angle will change in 45 degree increments. You can also find this option at the design panel.</p>
<h2 id="scale-elements">Scale elements, texts and properties</h2>
<p>Activate the scale tool by pressing <kbd>K</kbd> or from the main file menu to scale elements while maintaining their visual aspect. Once it is activated you can resize texts, layers and groups and preserve their aspect ratio while scaling their properties proportionally, including strokes, shadows, blurs and corners.
<h2 id="aling-distribute-layers">Align and distribute layers</h2>
<p>Aligning and distributing layers can be found at the top of the Design panel. </p>
<h3>Align layers</h3>
<p>Aligning will move all the selected layers to a position relative to one of them. For instance, aligning top will align the elements with the edge of the top-most element.</p>
<h2 id="layers-search">Search and filter layers</h2>
<p>Reach specific layers with a simple search. You can also filter the layers list per layer type (board, group, mask, component, text, image and shape).</p>
<li>Press <strong>Copy/Paste as... > Copy as CSS</strong> in case you only want to get the CSS properties from the selected layer/s.</li>
<li>Press <strong>Copy/Paste as... > Copy as CSS (nested layers)</strong> in case you only want to get the CSS properties from the selected layer/s and all the contained layers.</li>
<p>It is possible to combine shapes in a group in different ways to create more complex objects by using
"boolean" operators. Boolean operators are non destructive and the original shapes remain grouped and available for more editing. There are five boolean operations available: union, difference, intersection, exclusion and flatten. Using boolean operations allows many graphic options and possibilities for your designs.</p>
<li><strong>Union:</strong> the resulting combination is the sum of the shapes.</li>
<li><strong>Difference:</strong> the opposite of union, the resulting object has the area of the shape on top has been cut out from the shape at the bottom.</li>
<li><strong>Intersection:</strong> creates a group whose shape is the overlapping area between the shapes.</li>
<li><strong>Exclusion:</strong> the opposite of intersection, the resulting shape is the area that does not overlap between the shapes.</li>
<li><strong>Flatten:</strong> Tecnically not a boolean operator, this is the way to permanently combine the paths of a group of shapes in a single one.</li>
</ul>
<h2 id="constraints">Resizing constraints</h2>
<p>Constraints allow you to decide how layers will behave when resizing its container.</p>
<h3>Apply constraints</h3>
<p>Constraints allow you to decide how layers will behave when resizing its parent container. You can apply horizontal and vertical constraints for every layer.</p>
<p>To apply constraints select a layer and use the constraints map or the constraints selectors at the design panel.</p>
<p>Select the elements of a page you want to work with in a specific moment hiding the rest so they don’t get in the way of your attention. This option is also useful to improve the performance in cases where the page has a large number of elements.</p>
<p>To activate focus mode:</p>
<ol>
<li>Select one or more elements.</li>
<li>Right click to show the menu and select the option "Focus on" or press <kbd>F</kbd>.</li>
