.SH GETTING STARTED
|

|

The easiest way to get started theming rofi is by modifying your existing theme.
|
||||
Themes can be modified/tweaked by adding theming elements to the end of your
|
||||
config file. The default location of this file is \fB\fC~/.config/rofi/config.ras\fR,
|
||||
if the file does not exists, you can create it.
|
||||
|
||||
.PP
|
||||
For example if we want to change the \fB\fCType to filter\fR text in the entry box:
|
||||
|
||||
.PP
|
||||
.RS
|
||||
|
||||
.nf
|
||||
entry {
|
||||
placeholder: "Type here";
|
||||
}
|
||||
|
||||
.fi
|
||||
.RE
|
||||
|
||||
.PP
|
||||
In the above statement, \fB\fCentry\fR indicates the widget, \fB\fCplaceholder\fR is the
|
||||
property we want to modify and we set it to the string \fB\fC"Type here"\fR\&.
|
||||
To find the commonly available widgets in rofi, see the 'Basic structure' section.

For the next modification, we want to add the icon after each text element and

## GETTING STARTED
|
||||
|
||||
The easiest way to get started theming rofi is by modifying your existing theme.
|
||||
Themes can be modified/tweaked by adding theming elements to the end of your
|
||||
config file. The default location of this file is `~/.config/rofi/config.ras`,
|
||||
if the file does not exists, you can create it.
|
||||
|
||||
For example if we want to change the `Type to filter` text in the entry box:
|
||||
|
||||
```css
|
||||
entry {
|
||||
placeholder: "Type here";
|
||||
}
|
||||
```
|
||||
|
||||
In the above statement, `entry` indicates the widget, `placeholder` is the
|
||||
property we want to modify and we set it to the string `"Type here"`.
|
||||
To find the commonly available widgets in rofi, see the 'Basic structure' section.
|
||||
|
||||
To change the mouse over cursor to a pointer, add:
|
||||
|
||||
```css
|
||||
entry {
|
||||
placeholder: "Type here";
|
||||
cursor: pointer;
|
||||
}
|
||||
```
|
||||
|
||||
For the next modification, we want to add the icon after each text element and
|
||||
increase the size. First we start by modifying the `element` widget:
|
||||
|
||||
```css
|
||||
|
||||
element {
|
||||
orientation: horizontal;
|
||||
children: [ element-text, element-icon ];
|
||||
spacing: 5px;
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
Resulting in the following packing:
|
||||
|
||||
```

||||

|
||||
└─────────────────────────────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
The `element` (container) widget hold each entry in the `listview`, we add the two
|
||||
pre-defined children in the order we want to show them.
|
||||
We also specify the packing direction (`orientation`) and the spacing between the children (`spacing`).
|
||||
We specify the space between the two children in absolute pixels (`px`).
|
||||
|
||||
To increase the icon-size, we need to modify the `element-icon` widget.
|
||||
|
||||
```css
|
||||
element-icon {
|
||||
size: 2.5em;
|
||||
}
|
||||

|

|
||||
|
||||
In this example we specify the size in the [em](https://www.w3.org/Style/LieBos3e/em) unit.
|
||||
|
||||
Now lets change the text color of both the `entry` and the `element-text` widget to red and background to blue.
|
||||
|
||||
```css
|
||||
entry, element-text {
|
||||
text-color: red;
|
||||
background-color: rgb(0,0,255);
|
||||
}
|
||||
```
|
||||
|
||||
Here we use two different methods of writing down the color, for `text-color`
|
||||
we used a named color, for `background-color` we specify it in `rgb`.
|
||||
We also specify the property for multiple widgets by passing a comma separated
|
||||
list of widget names.
|
||||
|
||||
If you want to center the text relative to the icon, we can set this:
|
||||
|
||||
```css
|
||||
element-icon {
|
||||
vertical-align: 0.5;
