css3 adaptive control mobile phone text does not overlap

During adaptive zooming, it was found that the text overlapped when zooming to the phone.

At this time, you can use the media query method to set the Div text spacing with the letter-spacing attribute to achieve adaptive text non-overlapping.

@media only screen and (max-width: 568px){
    .index-title{
        letter-spacing:0.02em;
    }
}
