Can I install SPIFFS for Wemos D1 Mini Lite (ESP8285 chip) to use JS, HTML and CSS files as a stand alone webserver

I am looking to create a standalone webserver using the Wemos D1 Mini Lite (this is the only wifi microcontroller I have and cant afford a different one atm).

I know SPIFFS works with ESP32 chips, but can I use it with ESP8285 chips?

Looking to have HTML and CSS for the webserver, with JS scripts to run functions (At the moment only functionality is turning LEDs off and on), all uploaded to the Wemos and run from that.

JS CODE

const button_LED = document.getElementById(  "button_ToggleLED" )
const cb_red = document.getElementById ( "colour_red" )
const cb_yellow = document.getElementById( "colour_yellow" )
const cb_green = document.getElementById( "colour_green" )

let clickCheck = false

button_LED.addEventListener( "click", (event) => {
    //consoleLEDStatus()
    if (clickCheck) {
        button_LED.innerHTML = "Turn LED: ON"
        turnOFFLED()
    }   
    else if (!clickCheck) {
        button_LED.innerHTML = "Turn LED: OFF"
        turnONLED()
    }
    clickCheck = !clickCheck
})

//  A quick function you can run to check in dev console the status of LED
function consoleLEDStatus() {
    console.log(`LED Status:
       RED:        ${cb_red.checked}
       YELLOW:     ${cb_yellow.checked}
       GREEN:      ${cb_green.checked}`)
}

function turnOFFLED() {
    //  Insert function to turn off LED
}

function turnONLED() {
    //  Insert function to turn on LED
}

CSS CODE

/* Test class for checking Div borders. Uncomment to see them*/
/*
.border{
    border: black 2px solid;
}
*/

.mainDiv{
    margin-left: 20%;
    margin-right: 20%;
    padding: 10px;
}

.checkmarkDiv{
    padding: 10px;

.buttonDiv{
    padding: 10px;

.headingDiv{

#Header{

#button_ToggleLED{

    float: center;

Solution

SPIFFS has been replaced with LittleFS (Little File System) and it works on EPS8266, See LittleFS for more details.

The code example for using LittleFS to serve webpage can be found at FSBrowser example. It is a quite comprehensive example, you probably only need to implement part of it.
