📖 How to use
CSS Injector can be used importing the JS code via CDN or as a module using NPM
🚀 With CDN
<script src="https://cdn.jsdelivr.net/npm/@mobiloud/ml-css-injector/dist/ml-css-injector.min.js"></script>
<script>
(function(){
addStyle({css: `a{color: red !important}`});
addStyle({css: `a{color: yellow !important}`, regex: /\/\?param$/});
addStyle({css: `a{color: green !important}`, regex: /.*/, name: "Global Styles"});
addStyle({css: `a{color: green !important}`, regex: /.*/, name: "Global Styles", logs: true});
})()
</script>
Configuration options:
// accepts any styles as a string
let style = `
a{
color: green;
background-color: yellow
}
.className {
font-size: 2rem
}
`
// accepts regex enclosed within slashes
let regex = /.*/
// accepts string
let name = "Style name"
//boolean --> Prints logs in console for debugging
addStyle({css: string, regex: string, name: string, logs: boolean});
addStyle({css: `color: red !important`}) // if no regex passed, the styles applies to every page
Recipe for multiple styles:
// accepts any styles as a string
let styles = [
{
css: `
a{
color: green;
background-color: yellow
}
`,
regex: /.*/,
name: "Global Styles"
},
{
css: `
.cart{
color: green;
background-color: yellow
}
`,
regex: /.*\/cart/,
name: "Cart page"
},
{
css: "div.login{display: none}",
regex: /.*\/login/,
name: "Login page"
}
]
// accepts regex enclosed within slashes

addStyle({
css: e.css,
regex: e.regex,
name: e.name,
logs: true
})
} )

Testing the Injector
You will definitely want to test the CSS Injector once you deploy them to your website, to make sure that everything works and looks as you want.
Running these tests on real mobile devices can get overwhelming, so we recommend that you run your tests on your desktop browser.
To do this, you will need to emulate a mobile device by adjusting your browser’s user agent. We recommend using the following Chrome extension to do this: User Agent Switcher and Manager
Once you have installed the extension, set it up as follows:
Step 1
Select “Chrome” as the browser and “Android” as the platform if you want to test the Android version of the Button, or “Safari” and “iOS” in case you want to test the iOS version:
Step 2
Select one of the options that will appear, any will work:
Step 3
Click “Apply” to make sure the user agent is properly set up on your browser:
Step 4
You can now press “F5” while viewing your website to refresh the browser window with the updated user agent.
Reset
If you want to revert the changes to the user agent, as some websites might start behaving differently after doing so, you can click the “Reset” button:
