11 `paper-input` is a single- or multi-line text field where user can enter input. | |
12 It can optionally have a label. | |
13 | |
14 Example: | |
15 | |
16 <paper-input label="Your Name"></paper-input> | |
17 <paper-input multiline label="Enter multiple lines here"></paper-input> | |

20 -------- | |
21 | |
22 Set `CoreStyle.g.paperInput.focusedColor` and `CoreStyle.g.paperInput.invalidCol
or` to theme | |
23 the focused and invalid states. | |
24 | |
25 To add custom styling to only some elements, use these selectors: | |
26 | |
27 html /deep/ paper-input[focused] .floated-label { | |
28 /* floating label color when the input has focus */ | |
29 color: green; | |
30 } | |
31 | |
32 html /deep/ paper-input .focused-underline, | |
33 html /deep/ paper-input .cursor { | |
34 /* line and cursor color when the input has focus */ | |
35 background-color: green; | |
36 } | |
37 | |
38 html /deep/ paper-input.invalid[focused] .floated-label, | |
39 html /deep/ paper-input[focused] .error-text, | |
40 html /deep/ paper-input[focused] .error-icon { | |
41 /* error text, icon, and floating label color when input is invalid */ | |
42 color: salmon; | |
