# Mobile CSS examples

### How to control text size on mobile/ smaller devices

All of the font sizes in Design Packs are controlled by CSS variables, so you can update the size of text depending on the screen size. Copy and paste the following code into the Mobile CSS and change the values to see the font size adjust.  These pixel sizes will grow or shrink based on how large you have set the size with the "Text size" slider.

\--dp-heading-size will affect all of the larger h1, h2 headings (default size is 35px)\
\--dp-small-heading-size will affect the smaller headings such as h3, h4, h5, h6 (default size is 24px)\
\--dp-body-size will affect paragraphs, buttons, product titles, etc (default size is 18px)

```css
{
--dp-heading-size: 20px;
--dp-small-heading-size: 18px;
--dp-body-size: 13px;
}
```

If you would prefer to hardcode the font size (it will NOT change when the "Text size" setting changes, then use the following code and update the pixel values to your preferred numbers.

```css
.dsgn-pck__heading {
  font-size: 20px;  
}

.dsgn-pck__small-heading {
  font-size: 18px;
}

.dsgn-pck__text p {
  font-size: 18px;
}

.dsgn-pck__text a {
  font-size: 18px;
}

.dsgn-pck__button {
  font-size: 18px;
}

```
