You can get inspiration from this article: http://xlinesoft.com/blog/2013/10/26/building-a-nice-looking-login-page-with-custom-css/
Here it is the sample code the "Add new" button:

The code gives error and when i have checked in chrome inspect element it says invalid property value.
Secondly its adding image at background however i wants to add icon/image on left of the button just as it shows in new menu tool (as an icon)

path/to/the/add/image is only a sample. You have to replace it with the real path of your image.

Using Chrome inspector, check the CSS of the menu and update the button as per your needs.

Use Firebug for Firefox or Developer Tools for Chrome to inspect elements.

I used but for the above 3 there is no ID, may be its a missing thing thing in PHPRunner?

For the button on the Login page you can try the following:

I used below code but it does not apply properly, it applies some of CSS code but not all

Secondly what about other buttons like

logout

reset password

submit on password reminder page

"back to login page" on password reminder page
Another think on Register page "Register" button has same ID as Save button ID "
I suggest to add ID for all these buttons in next build.

Tayyab,
we will consider adding IDs to all buttons and also we'll make sure that images can be added to all buttons without causing CSS conflicts.

Here is a better way of adding icons to buttons via :before pseudo-element

Here is the List of button IDs you can use

addButton1:before - 'Add' button on the List page

saveButton1:before - 'Save' button on Add/Edit pages

.function-login a.main:before - 'Submit' button on the login page

.function-remind a.main:before - 'Submit' button on Password reminder page

.function-change a.main:before - 'Submit' button on Change password page

resetButton1:before - 'Reset' button on Add/Edit pages

viewPageButton1:before - 'View' button on the Edit page

backButton1:before - 'Back to List' button on Add/Edit/View pages

editPageButton1:before - 'Edit' button on View page

inlineAdd1:before - 'Inline Add' button on the List page

extraButtonsToggler1:before - 'More' button on the List page

selectButtonsToggler1:before - 'With selected' button on the List page

Sample List page with a few icons added:
