This article contains a simple tutorial on how to edit the style of line features in the map - mainly roads and streets. In case you are interested in deeper and more complex map styling, please visit the following article: Advanced customization.
Open your profile at MapTiler Cloud and select the map in which you want to edit the style.
In our case, it is the Streets Map.
Click it and you shall see the preview of the map with several predefined styles and hyperlinks for displaying the map in various online viewers. Go and click the three dots button and then Edit a Copy.
MapTiler Style editor will open and you will be able to edit the style of the entire map with all its features and objects.
Focus on the left panel where you can find the individual layers. On the right-hand side, there is the map preview window. This is where you can see your style edits in real-time (e.g. missing road label).
If you want to change the visibility of a particular layer (road labels), click the little eye right next to the name of a layer. Your layer will either appear or disappear. There are other features that you can edit as well, such as visibility of a feature throughout the different zoom levels, transparency, labeling, and so on. All these features can be found in the menu on the left. For more detailed info about these editing options, please visit the article about Advanced customization.
The same principle applies if you want to change the style or visibility of the road labels (they are called highway shields in the map).
For advanced styling options, there is the JSON Editor, where you can see and edit your style features directly in the JSON code.
You can also make the entire roads disappear, just as shown in this example, where the entire Lower Train Station in Brno just vanished.
Once you are satisfied with the result, click SAVE and then CLOSE.
Your map will be saved and it will appear among other maps in the section My maps.
You can work with your newly styled map from here. You can publish it via various tools and services. And here is more info about how to Publish your geodata.
