How does the "get" method differ from "post" in form data submission?
- "get" displays the submitted data in the URL; "post" does not.
- "get" encrypts the submitted data; "post" sends data as plain text.
- "get" has no size limitations; "post" has size limitations.
- "get" sends data in the HTTP header; "post" in the body.
The "get" method appends data to the URL in name/value pairs, making it visible in the browser's address bar. It's mainly used for fetching data. Conversely, "post" submits data within the body of the HTTP request, making it more secure for sending sensitive data and appropriate for sending large amounts of data.
The ______ attribute is a boolean attribute that specifies whether an input field must be filled out before submitting a form.
- mandatory
- necessary
- obligatory
- required
The required attribute is a boolean attribute that indicates whether an input field must have a value before the form can be submitted. If an input field has the required attribute, and the user tries to submit the form without filling that field, the browser will display an error message prompting the user to input a value. This attribute ensures that crucial information is not missed when a form is submitted.
Your client wants an easy way for website visitors to contact them via email, with the subject and body pre-filled. How would you implement this using mailto: links?
- Use a form with POST method to send emails.
- mailto:[email protected]#subject=Hello&body=Message
- mailto:[email protected]/subject=Hello/body=Message
- mailto:[email protected]?subject=Hello&body=Message
The mailto: scheme can be extended with parameters to pre-fill the subject line, body, and even CC or BCC fields in an email. The format is: mailto:[recipient]?subject=[subject]&body=[body]. This creates a seamless experience for the user, allowing them to simply click the link to open their email client with a pre-populated message.
Your website analytics show that users are struggling to navigate through the site using keyboard controls. How would you reassess and modify the tab order and access keys to improve navigability?
- Assign all interactive elements a tab index value of "0".
- Conduct user testing focusing solely on keyboard navigation.
- Reorder tab sequences based on the page's visual layout.
- Use analytics to identify less-visited sections and remove their tab order.
User testing focused on keyboard navigation will provide first-hand insights into the issues users are facing. This direct feedback can help identify problems in tab sequences and access key assignments, allowing for effective, user-centered improvements.
Using the CSS “line-height” property on a ______ tag helps to adjust the space between lines in a paragraph.
The CSS property "line-height" determines the amount of space above and below inline elements, which is most commonly applied to text. When applied to a
(paragraph) tag, it adjusts the vertical space between lines, enhancing readability. This is crucial for long-form content to ensure the text is comfortably readable across various devices and screens.
How can CSS grid layout be utilized to recreate complex table layouts without using the traditional table elements?
- By only using grid columns.
- By setting grid-template areas.
- By using the display: table property.
- Grid can't recreate table layouts.
CSS Grid Layout is a powerful layout system that can replicate complex layouts, including what traditionally might have been done with tables. By defining grid template areas, one can visually map out "cells" and "rows" akin to a table structure. The advantage is that you gain the responsive and dynamic capabilities of the grid, allowing for more flexibility in reformatting content based on viewport dimensions and other conditions. It's essentially creating a "table" without being confined to the semantics and limitations of the traditional table elements.
What is the primary strategy used to make a table responsive?
- Adjusting table font size.
- Breaking the table into rows for narrow screens.
- Using CSS grid.
- Using the
tag.
To make tables responsive, especially on smaller screens like mobile devices, a common strategy is to transform the table into a block-like layout where each row behaves like a separate section. This can be achieved using CSS and sometimes with the help of JavaScript. This approach ensures that content remains accessible and readable on all devices without horizontal scrolling.
To create a password field, the input element should have a type attribute set to ______.
- checkbox
- hidden
- password
