When it comes to deploying an IoT application to end-users, a big portion of the user reception and adoption of the solution is related to the look and feel of whatever they're using, if it's catchy and nice to the eye, this undoubtedly helps changing the perspective and makes the on-boarding easier.

For that reason, besides Ubidots' basic customization options at the App branding level, there's an advanced editor for dashboards and widgets providing additional options to change their aspect even further.

The advanced customization feature is a JSON-based editor where users can input element-defined keys to set parameters for the look and feel of each of the available elements. Here's an example of how it looks at the dashboard level:

IMPORTANT NOTES:


This feature will override any customization set at the App level.

Step 2: Open the settings by clicking the sprocket option on the right side.
Step 3: Click on the "Custom Style" option, located in the Appearance section.
Step 4: Input the JSON-based file in the editor to indicate the desired customization.
Example: Note that every text different from a number needs to be wrapped up in double quotes as a string. 

{
    "widget": {
        "color": "#5e5e5e",
        "header": {
            "color": "#ffffff",
            "backgroundColor": "#202d4d",
            "borderRadius": 0
        },
        "fontSize": 14,
        "fontFamily": "Helvetica",
        "boxShadow": "3px 3px 5px 6px #cccccc",
        "fontWeight": "normal",
        "borderRadius": 7,
"borderStyle": "solid",
"borderColor": "#5e5e5e",
"borderWidth": 1,
        "backgroundColor": "#ffffff"
    },
    "dashboard": {
        "color": "#5e5e5e",
        "backgroundColor": "#f2f2f2"
    },
    "contextBar": {

  4. By default, the unit for the numerical key is px. If other is to be used, it needs to be specified.
    Examples: "fontSize": "1.5rem" – "fontSize": "1.5em" – "fontSize": "70%"

2. Custom style from Widgets

Add a linear gradient overlay to a background image


You can add a color gradient or a semi transparent color on top of a background image in Widgets and Dashboards by using the key background in the custom style, where the first parameter is linear-gradient(), and the second one is the image's URL. Learn more here.


{
"color": "#5e5e5e",
"header": {
"color": "#5e5e5e",
"backgroundColor": "#ffffff"
},
"fontSize": 14,
"background": "linear-gradient(to right, transparent, mistyrose), url(<IMAGE_URL>)",
"borderRadius": 20,
"backgroundColor": "#ffffff"
}

3. Custom style: HTML canvas widget

The HTML canvas widget allows users to create their own widgets in order to fit visualization needs that are not necessarily available within Ubidots default widget palette.
In this section, you'll learn to change this widget's header styling in a dynamic fashion right from the JavaScript code. 

Step 1: Create a HTML canvas widget.
Step 2: Open the HTML editor.
Step 3: Paste the below code in the corresponding tab
HTML

<button id="color">Click here to change header styling</button>

JavaScript

const button = document.querySelector("#color");
button.addEventListener("click", () => {
    const event = new CustomEvent("widget_changeHeaderColor", {
        detail:{
            "backgroundColor": "#00bcd4",
            "borderRadius": 7,
            "color": "#ffffff",
            "boxShadow": "3px 3px 5px 6px #cccccc",
            "fontWeight": "bold"
        }
    });
    document.dispatchEvent(event);
});

Step 4: Click on the green check-mark button
Step 5: Click the green check-mark button in the dashboard settings.
